I think we're probably just not going to see eye to eye on this. I specifically didn't want to get dragged into this whole tarpit of tribal bitterness, but then I waded into it deliberately on purpose, so that's on me I guess.
I actually wrote and then just deleted some stuff, because what's the point. I feel like I've said what I had to say on it and you have a differing point of view. All good. I'll leave only the thing I think gets to the heart of it:
If blahaj admins would just be straight-up about it, and say "Listen. This dragon person is clearly a troll, and we're banning them for that reason, but we don't want to allow people to decide pronouns on a case-by-case basis. In this case, the rule produces a stupid result, but that's the rule we settled on and we have good reasons not to bend it in any circumstance or have to have long debates about this stuff every week, so please respect it or we will ban you," I don't think there would be any kind of issue. That's a decent and human-to-human way of defining the interaction that gets across the point and still respects their good reasons for the rule. To me (and maybe you may disagree with this), it seemed like instead of that they said "HOW DARE YOU MISGENDER THIS PERSON YOU TRANSPHOBIA ADJACENT BIGOT" and then went on to (as in the current post) continue to whine about how horrible it was that anyone was trying to point out that (a) the user in question was clearly a transphobic troll (b) going to bat for them was ridiculous. And, they constantly talk about how those people were wrong, and bigoted, and shouldn't be talking that way even off the blahaj instance.
That's my take on it, I don't think I want to go back and forth about it much much more, you're welcome to the final word if you like.
