Yes, that one user is quite annoying because they make things sound well researched, when they frequently aren’t. I’ve seen that user around, and I just don’t engage with them anymore.

But the rest of the instance isn’t like that. Yeah, there are some tankies and whatnot there, so I’m hesitant to sub to anything political on that instance, but most of the rest of their users are totally fine. Their users don’t typically attack other users, so you’re only really affected if you choose to engage, and you can stop at any point.

So that’s why I disagree with defederation. If a user on their instance harasses you, report it. If the admins of that instance do nothing, report it to admins here. If there’s a pattern of their admins allowing harassment, we should defederate.

But having stupid ideas isn’t grounds for defederation imo.
