So I just finished reading The Catcher in the Rye, call me generic or whatever but I want more books like this...

As dumb of a 15 year old as I was, I was smart enough not to like it, correct.

This Side of Paradise, by Fitzgerald. It had the same effect on me. Then you can read Sentimental Education, by Flaubert. It's better to read Coming of Age novels then YA shit. In no time you'll be into deeper stuff. Keep it up.

You don't have a sincere bone in your body. This book is screaming at you

Then read everything he wrote, it's not like he published much. Nine Stories, Fanny and Zooey, and Rise High the Roof Beam, Carpenters/Seymour: An Introduction.

Absolute brainlets

There's a lot of stuff like this (and imo much better done) in Japanese literature. But well, you have to learn Japanese.

the japs are gay

A Clockwork Orange

What did you think of the part where Holden raped Phoebe?
Also don't listen to the midwits, Catcher is famously a 'bell curve' book where brainlets love it, midwits hate it, and patricians love it.

Raise High the Roof Beam, Carpenters is similar to Catcher in that it also has first person narration. It's really good, if you liked The Catcher in the Rye you'll probably enjoy it.
