Check out r/Libertarian sometime. After it was radicalized by self-professed fascist moderators and turned into a pro-Trump meme board, the admin stepped in and installed a moderation team that spent time coming up with rules to prevent the subreddit from being overrun by authoritarians again. They added legitimate left-libertarian[1] moderators, and there are left-libertarians users that post there.

I bring it up because it is the only conservative space I've seen that doesn't end up posting helicopter ride[2] memes at people they perceive to be even slightly to the left of them.
