The problem with this idea is that lemm.ee does not have strong moderation and content rules, and that is the exact sort of environment that extremism worms its way into and takes advantage of. I don't expect the admin team to have the time to police the community with a fine enough comb to catch all of the bad content, and I don't trust the moderators of any self-titled conservative community to do that job properly.
These communities are ultimately more trouble than they're worth, and as such I would prefer to see them shunted away from the major servers. Let them build their own hexbear, lemmygrad, or ml. But I don't think that their regressivism and bigotry have any place here.
I wish these officials would stop taking the coward's way out and instead choose to stay and keep fighting until forcibly removed by security.
