I don’t think it makes it unworkable, but I think it warrants a democratic process in this kind of decision making. We as a society should shift away from the mindset of “this is my ball, you just get to play with it” and embrace the idea that forming instances is a form of mutual aid (maybe that’s part of why I’m a mod there lol). I think hexbear culture might leak a bit, but I think you’re right that it will mostly stay there (also I personally I enjoy their style of humor).
As for moving the community, I would like for it to stay here. We aren’t big or active enough to get a migration to occur, and most of the alt instances already have a leftism community. If the admins want to pivot to strictly no politics, then fine I guess
