Okay, well—you earned it: You should feel ashamed of yourself. He may not agree with you, and if you haven't noticed I am not the same as this imaginary character you've imagined in your mind that you have self-appointed yourself some right to beat on—contrary to half the delusions coming out of your & a few other people's mouths.

Calling someone "autistic" and an idiot for disagreeing with you in such a calm, collected manner shows that you are filled with bigotry & projecting criticism onto others. There is a difference between having passionate conversations, a sarcastic playful sense of humor about it—and simply being a pretentious, cold critic with a false sense of superiority. Process your shame, talk to him in a healthy way, then move on; learn to apologize. It doesn't mean you are wrong.

Really, though, I'm probably wasting my time here trying to educate you; not because you are incapable, but you'll grow up at your own leisure
