I had an autistic golem (literally, 6'3, 250lbs or so) try to rip my head off one time because I called him out on his hypocrisy. This school I used to go had a lot of SPEDs and whatnot, mostly because it focused on STEM, something that attracts these type of people. This same retard once pissed in some girl's Stanley thermos and took videos of girls without them knowing. Obsessed gooner, some shit like that.
I told some random stupid joke and he tried to take the moral high ground "erm... that's racist...". I mentioned that he had made the same joke before and that he often threatened to rape any black guy that went past him. Nothing much really happened after that but we had to go to the principal's office adn that's when he tried to kill me.
