This would also change the context, but I haven't heard anything else about this, which again is why I'm deciding to pay more attention, but not quite ready to demand any sort of community uprising against him.
It is unfair to Matthew Butterick and to anyone in his situation.
Like, I think the thrust of the claim here isn't that you're necessarily arguing in bad faith or something. It's more likely a sense of frustration that something which is so relatively out in the open and obvious is even being "contested" at all (not to shove words in your mouth but just for lack of a better one.) And to be fair to you, this dynamic of "open secret" is very common with abusers, for the literal exact reasons Butterick outlined in the post. So it's not like an original sin or anything...
No one asks you to crucify anyone. Nor to pay attention to that community. If it is pit od way for you that is perfectly fine.
What I took issue with is that reflexive impulse to assume that if someone complains about bad treatment, that person much be wrong, weak or some such.
