I have an autistic coworker who used to say really uncomfortable things to museum guests while making small talk. like bringing up active, controversial revolutions in their countries if they were international, and such. finally, after a group of Hawaiian guys got visibly angry when he asked if they were "in the military or just rich" to be able to live there- meant to be a cost of living joke -I said, "hey, personally, I try not to talk politics with guests. sometimes it may upset them and we don't get paid enough to deal with that"
he looked thoughtful and said, "oh, I never considered it that way." turns out he was just a geopolitics nerd and didn't realize people might react emotionally to what he saw as a purely intellectual discussion
