Calling into question the functioning of someone’s brain is pretty neuronormative.

I’m not being that serious though, because I also can’t find any example of someone being ableist to you beyond calling you stupid (it was me, I did that).

Hexbear has probably the lowest tolerance for ableism of any place I’ve seen on the internet. The raiding parties you see coming into your instance to bash liberals on the internet and correct their disinformation are not really representative of the tone of conversation on the actual instance itself between people who aren’t spoiling for a rumble, not that I would expect ableism even then. The mods of Hexbear are very strict about that kind of thing, so watching clown-to-clown communication between you and your buddy as you just outright lie on the internet about the nature of another online community, in a farcical echo to how your forebears fabricated lies about socialist states, demanded comment.
