The instance seems to be mostly right wing trolls. I know defederating is unpopular but I don't think much is to be lost in this case and it can save the mods some headaches.

Maybe lemmygrad, but Beehaw is hardly radical because they did a temporary defederation because they didn't have the manpower to deal with users breaking their community rules.
I would say beehaw is more extreme than lemmygrad. Lemmygrad may have fringe extremist views, but their behavior on social media is rather tame (at least in my experience). Whereas beehaw may have more "tame" views, they're much more extreme in their moderating.
