If you want to make the world a better place for mentally ill and neurodivergent people, get into the habit of shutting down people who mock/laugh at/sneer at “odd” or “weird” but harmless behaviour. Just refuse to laugh with them and say “That’s not funny.” or “They’re not doing any harm.” Do this whether or not anyone who’s directly negatively affected hears it. This is both about protecting people from ableist verbal abuse, AND about teaching ableists that their attitudes are not being tolerated and that you’re not going to bond with them over ableism (or, hopefully, any other form of oppression).
good post
My fav is saying “I don’t get it” or “what’s the problem/joke?” and forcing people to admit that they’re just being assholes.
