Yes and no. Yes, there is no Fediverse-wide admin to moderate content since everything is decentralized, but instances and their subcommunities do, and each one is free implement their own rules. We're on Beehaw, which is pretty strongly committed to fostering a community with a positive culture and tone, and while there is a good amount of leeway for free discussion (from what I've seen in just 2 weeks here), I imagine getting too vocal about wishing that kind of thing might get attention from the Beehaw mods at some point.

Not that I don't fully understand your emotions.
