My friend dosen't know basic public mannerisms and how to talk to people

Why are you friends with him? When parents tell you that people judge you by your friends, it's because people judge you by your friends. To take the argument to a ridiculous extreme, wouldn't you side-eye someone who knowingly hung out with a rapist or an animal abuser? Your friend is utterly socially repugnant and cruel. He truly doesn't sound like a nice person. I'm on the spectrum (this means some form of autism) and I can be socially awkward, but never cruel. Telling someone to SHUT THE FUCK UP the way he did is beyond crass; it's abusive and controlling. If you take a step back and examine how he treats you, it probably isn't much better. Try staying away from him for a couple of weeks and see if you actually miss him or if it's a relief not to deal with him anymore. He may have a few good qualities, but they cannot possibly outweigh the behaviours you describe.
