Maybe start by not conflating privacy with concerns about censorship.

Then, it'd be great if privacy-focussed platforms would show a commitment to find privacy- and freedom-preserving ways to tackle the very real problem of these platforms overflowing with actual, self-marking Nazis.

As an analogy: if the cryptocurrency community can find ways to curb problems such as scams or the waste of energy with technology, it can avoid the regulation to that effect it so much fears. But every time some cryptobro opines that people really deserve to be scammed if they did not go through each single line of source code their bitcoin wallet depended on, the idea that these communities are sticking up for some larger values and not feeling quite ok with scammers and Nazis loses a bit more of its legitimacy.
