Yeah I don't know if I have autism or whatever but I do know that I can't fucking concentrate with a dozen people having loud conversations 5 feet away from me. I don't think this makes me "weird" - there's a long history of letting people who are asked to concentrate like exam-takers, at least, the courtesy of silence. But if "be nice to autistic" people is what we have to say in order to get a return to basic human decency, so be it.
