There are communities, for example, that block other communities that are 'freespeechers'. i.e. communities that don't ban people for sayign things that the former community operator deems as racist. At first I was like, "that's messed up, it's too subjective". But then I remembered that actually, unlike Twitter, that decision to block the people didn't affect me. They're allowed to create their own community how they want, and I'm empowered to join or self-host my own.
Pretty cool that vulnerable and very very helpful communities have tools like this.
