I saw that kind of shit behavior in an old fandom of mine.

Me, I don't give a shit if you have Asperger's, are autistic or whatever. If you tell me, I'll shrug and be like "Okay." But if you use it constantly as an excuse to be a stupid prick to everyone else, fuck you and the horse you rode in on. I have friends with those same disorders who'd never do that kind of crap, and if you're a very low functioning autistic, you shouldn't be picking fights on the internet anyway.
