I agree that we do not have good ways of dealing with abuse and abusers. I also think that we need to be much more into shouting at each and much less into treating disagreement as a reason to drive people out.
The Bad Space thing is a good example. I'm sure they genuinely thought that Nina and others were racist. They should have been taken seriously, but even if they were right, Nina should not have been ostracised. On this assumption, she is just wrong. They had a political disagreement. She wasn't and isn't a threat to anyone. She doesn't want black people dead, enslaved or out of society. if you take that view, bad faith actors can't manipulate what is in the end political disagreement to take power.
Even if they are not in bad faith, it is a still a problem. You end up requiring an arbitrator and then cops to enforce their decisions. In other words, you need a hierarchy. Policing speech is inherently conservative. It is seen in the way that mastodon.social excludes Palestinians because some Jews genuinely think that they are being antisemitic and the moderators are sympathetic. They are also enforcing their rules. The rules are bad. They require top down power. We should work to get rid of those dynamics by going back to shouting at each other.
