Why is step-sibling romance such a taboo in the US?

I dunno cleetus, you tell me.

Imagine dating no one before dating someone.
Stigma. These are the kinds of people who start talking about inbreeding but don't even consider heart conditions of non-blood related partners. Morons who believe what they are told and never ask a god damn question.

>you still have to act
No you dont you dumbass NPC. Stop worrying about what this broken society thinks

dude what's your point. it happens all the time but it's still weird because the parents don't like it and they want you to date other people.

>the parents don't like it
You base your beliefs on assumptions and don't stop to consider why you feel how you do about what you do.

Brady Bunch was a culture psy-op to discourage it

the point of families merging is to behave as if you are blood related. so it still will have the stigma of being weird and incestuous despite it not actually being. you're supposed to be friendly, protective, and supportive of your sister not fuck her. even though that happens too.

>stigma
Exactly.
>supposed to
Knowing what is best for others is delusion in most cases.

It really depends. It's weird for two children who grew up in the same house and treated each other like family to engage in a romantic relationship even though it's not necessarily wrong. Like it's weird for foster siblings to have a romantic relationship.

If you're nearing adulthood and your single parent marries someone with a kid around your age you start to develop feelings for, that's hardly weird at all though. These two people never knew each other as siblings.

>its not wrong
>but ill call it weird to imply i dont like it anyway
??

I knew a girl who started a relationship with her brother after they discovered they weren’t really blood related. They grew up together, that for me is more sick than a legit brother and sister getting together as adults having never met each other before.

>If you're nearing adulthood and your single parent marries someone with a kid around your age you start to develop feelings for, that's hardly weird at all though
Maybe, but you still shouldn't act on it because it fucks up the family

Why?

Paul Rudd and Alicia Silverstone are both jews. Its quite normal to have incestuous relationships in judaism.

why is it sick?

Yes goy, clan mentality and strong family ties bad! Move out at 18 and never talk with you parents, outbreed with some immigrants from 3rd world country when you are at that too!

>I dunno cleetus, you tell me.
It's funny because whites are less likely to engage in incest than other ethnic groups living in the United States.

It’s taboo everywhere retard. You mutts actually fetishize inbreeding and sibling romance the most. Just look at your pornsites and mainstream media.

I’ve always wondered how it must feel to have a 10/10 sister the same age as you. All mine are 10+ years older than me and ugly so it’s repulsive to think of them in that way.

Wrong and weird are different things.

Actual full blooded incest is wrong, but fucking your step sibling is merely weird depending on how much time was spent together acting like siblings.

>incest is wrong
Why?

youtube.com/watch?v=9SUrN3Nkp2k

Because it causes genetic defects, fucks up familial relationships, and most people have an natural aversion to it anyway.

Now, I don't think it should be illegal or anything, because consenting adults should be able to do whatever the hell they want to do, but it's still morally wrong for those reason.

so wear a condom lol

Marriage is a sham anyway. Why do two 18 years olds with no relationship to each other, other than their parents are going through s midlife crisis, have to pretend like they are blood relations who grew up together?

>genetic defects
So does mating with someone who has heart disease should that also be illegal? Should women over a certain age not be allowed to become pregnant due to the risks?
>fucks up family
An odd assumption. Drinking can fuck up a family, should that be illegal as well?
>most people have a stigma
So?
>don't think it should be illegal but it is morally wrong
The fuck is the point of this mentality? You see two people doing something legal and you judge them for their morals? Why live in a society that allows people to do what you believe is wrong?

What are you talking about, there's tons and tons of taboo step fantasy shit on pornhub

MAAAAAAAAAAAAAAAAAAAAAAX

people are clueless

There is nothing morally wrong with incest and when you debate anyone that's against it they can't come up with any points other than the feels of "b-but its wrong".

i hate that step sibling bullshit. it's no different than fucking a stranger on the street. either go full related or fuck off.

>Drinking can fuck up a family, should that be illegal as well?
Yes

How far should that be taken do you think?

its genetically wrong you retard. Step siblings are fine though since you aren't blood related

ITT: NPCs
There's a reason the wise ancients of Egypt and Persia considered incest sacred.

So is two people who have heart conditions having a child, should that be illegal?

no because they aren't blood related.

You said genetically wrong, blood would not matter in that case. Their child would have a much higher genetic chance of heart disease. How is it different?

Meh, more of a generational problem, no history you're probably better off than a 40 year old woman's offspring. Also half siblings have an innate attraction.

because in one situation you are simply taking a health risk, in the other situation you are taking a health risk + shitting on the sanctity of family.

So basically you are just relying on "muh feels" to make an argument and nothing more. Gotcha

At first it was genetically wrong now you bring morals into it. You are fine with two parents knowingly mating despite the higher chance of genetic defects but care for the "sanctity of family"? How is that different? What is sanctified about knowingly burdening one of your children like that?
Worse, he is just cognitively dissonant.

Most humans aren't attractive enough to warrant risking destroying your family life by fucking the shit out of your step-sibling

It needs to be warranted?

>this guy who keeps replying to everyone
Just fuck your sister or something, nobody fucking cares because she's ugly anyways

I don't need you to care for me to be right, user.

Be right about what? Most people don't want to fuck their sister because that's nasty. If you wanna fuck your ugly sister go ahead. I'm not gonna stop you just like I don't stop people who like to eat shit.

>that's nasty
Why?
>i'm not going to stop you
You don't have the power for that to be a choice.

I plainly stated its genetically wrong, then you tried to make some lame excuse about other genetic issues, which was true ( I never denied that) then I added the fact that it is also morally wrong. Whats not to understand here?

>Why?
because you a ugly ass nigga

Both would be genetically and morally wrong meaning you would logically want both to be illegal. But you don't despite them being the same.
You seem disingenuous. You'd approve of incest if the people involved where pretty? Do you enjoy watching pretty people fuck? Bit of a voyeur huh little pervert?

why is it people who defend incest are generally so intelligent and well-spoken? I'm impartial to this, just something I've noticed

Explain how it's genetically wrong, because it seems you are saying its genetically wrong but mean to say that you think its morally wrong because its family which is not an argument and just your feels acting up.

It is a hard thing to defend which makes it fun. People who are well spoken enjoy debating to show off and for the challenge. The same reason tall men play basketball.

it is both genetically and morally wrong. there is no grey area to what I'm saying. people with severe health issues also shouldn't be having kids but It's not my place to stop them.

>no because they aren't blood related.
So you have changed your mind then?
>not my place to stop them
Then why debate for them to be stopped, if it is not your place?

are you being intentionally daft? its not morally wrong for the people who aren't blood related but its still a genetic high risk.

It is not morally wrong to knowingly create a child with a much higher risk of genetic deficiency?

nope

Then why is it morally wrong for those who are blood related?

because you are 100% weakening the bloodline by doing so

Depends on the situation. If they grey up together as children that's just really weird, that's pretty much the same socially as fucking your actual sibling.

If they are like teenagers and their parents get married and then they are put together in the same house, practically strangers, raging hormones, how can you possibly expect them not to fuck?

Factually incorrect, you do not know what you are speaking on and are a fool for spreading lies.
Father/daughter or mother/son 50% (12)
Brother/sister 25% (14)
Grandfather/granddaughter or grandmother/grandson 12.5% (18)
Half-brother/half-sister, Double cousins 12.5% (18)
Uncle/niece or aunt/nephew 12.5% (18)
Great-grandfather/great-granddaughter or great-grandmother/great-grandson 6.25% (116)
Half-uncle/niece or half-aunt/nephew 6.25% (116)
First cousins 6.25% (116)
Why should society dictate who you love and who loves you?

>you're not blood but you still have to act and behave as if you were.

No, you don't.

you're the one spreading lies like its still the 1800's m8. we already know that it fucks your genetics when you mix with blood relatives.

It has the chance to, yes. Not 100% guaranteed, a chance. I posted the statistical likelihood in the post you just responded to. It is worse to have a child when the woman is 40 than to have a child with your sister, statically speaking.

>these random numbers with no scientific backing certainly prove my argument :)

It is quite literally one of the first things brought up when searching on the topic.

>1922
lmao

You're suggesting human DNA has changed in 100 years? Do I need to educate you on evolution next?

If you are playing the genetic defect angle, than be aware you you must also be against midgets having children or older women past 30 or anyone that has heart conditions or other ailments since all can be passed down. Also be warned this stance would be universally looked down upon by society as a whole, since you want to control or may or may not have sex.

>a study that is almost 100 years old is the only proof I have thats its ok for me to jack off into my sisters underwear

its a package deal friend, genetic defects and morally wrong. Genetic defects aren't optimal but when you combine that with morality, thats a big no no.

Both would be morally wrong as they cause the same problems.

Because everything is taboo in the US...except for the oddest fucking things now. Go figure. That's the fucking question. Why is this taboo or STILL taboo but making up and insisting upon fictitious gender pronouns is the "it" thing.
We had prohibition for fucks sake.

>So does mating with someone who has heart disease should that also be illegal?
Yes

ok fine, in an apocalyptic situation where humans are pushed to the brink of extinction, I will overlook siblings having sex with each other. but since we don't live in such extreme times the answer is no, you are fucked in the head for wanting to do this. If your entire point is simply thats its not "genetically as bad as X or Y" then congratulations I suppose, you've certainly convinced the world that incest is ok with this post, next I suggest that you try and convince everyone racism is ok if you're also racist towards your own kind.

How far would you take that?
>fucked in the head
That's your medical opinion? In any case when you want to concede just say so, I could care less for your bruised ego.

>of course there's nothing "wrong" with having romantic relations with underage children, and it happens all the time. but it's not a good thing socially to get out there.
>you're not abusing them but people still believe and behave as if you were.
>stop pretending to be an idiot now k thanks

Wow, that really redpilled me.

I literally just did friend. on a technical level incest is just as bad as any other unfavorable mating conditions (such as the ones you laid out) but its STILL worse because lol get fucked you loser. you may now tick another victory in your internet argument chart.

Clueless was ahead of its time

No, it was massively popular in its time and represented the 90s perfectly

Fucking your childhood friend is also incestous.

Because divorce is a retarded plague on our country that millennials are now just fixing. When we had 50% divorce rates or worse it was just getting weirder and weirder and you'd almost be having de facto arranged marriages with the kids of your shithead step parents.

Also there is this family roleplay LARP where you pretend like you are blood relatives in the USA, you try to pretend you are a strong family even when you are broken to save face, if you fuck your stepmom or sister then its losing face with the neighborhood or people think you are just a sex addicted pervert who can't wait for a "real normal relationship" you just fucked what walked in the door. Of course this country is not known for its subtlety.

If we can get divorce rated down to 25% say, you might see less step families because families are more planned and therefore less gross to people because they assume more likely you are genuinely in love with your step sibling and not just looking for a quickie with "family."

there is nothing wrong with having a loving sexual relationship with your sister.
its the purest love.
my sister and I have no issues with it.
