Okay.
> I’d like to punch him in the face
Okay. He would like to do something. Doesn't mean he will or that he things anyone should
> The man that was — I don’t know, you say “roughed up” — he was so obnoxious and so loud, he was screaming — I had 10,000 people in the room yesterday, 10,000 people, and this guy started screaming by himself. And I don’t know, “rough up” — he should have been, maybe he should have been roughed up. Because it was absolutely disgusting what he was doing.
"Maybe", and an expression of an opinion.
> You know, part of the problem, and part of the reason it takes so long, is nobody wants to hurt each other anymore, right? And they’re being politically correct the way they take them out, so it takes a little bit longer. And honestly, protesters, they realize it. They realize that there are no consequences to protesting anymore. There used to be consequences, there are none anymore.
This quote appears to be rather squarely targeted at political correctness, and seems to be referring to hurting people's feelings.
> I would never give up my microphone. I thought that was disgusting. That showed such weakness, the way [Sanders] was taken away by two young women — the microphone — they just took the whole place over…That will never happen with me. I don’t know if I’ll do the fighting myself or if other people will, but that was a disgrace…
This isn't a reference to violence, this is a reference to refusing to give in to someone taking over his appearances.
> “He was a guy who was swinging [punches] — very loud, and then started swinging at the audience and you know what, the audience swung back, and I thought it was very, very appropriate. He was swinging, he was hitting people, and the audience hit back. And that’s what we need a little bit more of.”
Regardless of whether this is an accurate portrayal of the situation, this is rather obviously a reference to self-defence
