Speaking as a moderator, moderating communities isn’t exclusively about ideology. I believe, ideologically, in freedom of speech - but I’m not going to let shitheads shit up my communities just because they have the legal or moral right to spout off. I have the right to keep a clean house - to not provide a platform to whoever wants it. Hell, this extends to the simply irrelevant - if someone, genuinely and innocently but insistently - started posting fantasy artifacts in !historyartifacts@lemmy.world, I would remove their posts in a heartbeat.

Freedom of speech doesn’t mean giving everyone your platform to speak out - anarchism doesn’t mean communities cannot be curated. Though, I believe, in terms of praxis it would mandate a more democratic means of curating communities, but as has been pointed out elsewhere in this thread, Lemmy’s not really got the tools for that.
