Let me preface this by saying that, from what I have seen in screenshots, there was no ableism against db, db was just not taking care of themself by compulsively replying and getting mad at people replying to their replies, like it's "ableism" to not let someone have the last word.

Which makes it really gross that they are taking the real complaints hexbears have had about the broader HB culture and cynically weaponized it by distorting the very concept of ableism. The real complaints that I've seen are almost the inverse, which are that certain comrades, particularly ones on a certain part of the spectrum, get labeled as "debate bros" and otherwise disparaged, getting comments deleted, sometimes even getting banned, when basically what happened was that they disagreed and were failing to let it go. There is such a thing as a "debate bro," and we encounter them here often enough, but it can also effectively become a progressive-sounding way of saying "this autist keeps participating in this argument and I don't feel like either engaging in good faith or ignoring it, so I'm going to just say they are a (white?) male chauvinist who is obliged to give me the last word."

I've seen this complaint from at least three or four different people, though I think most of them aren't around anymore.
