Going to bring it up again, the Paradox of Tolerance disappears when you consider tolerance a social contract rather than a moral standard.
Nazis base their identity and politics around not tolerating the presence of various minorities, and therefore aren't entitled to tolerance themselves.
TERFs base their identity and politics areound not tolerating trans people, and therefore aren't entitled to tolerance themselves.
Furries don't base their identity on excluding, invalidating or persecuting someone else, so furries are entitled to tolerance.
So, the furry boards stay but we need to defederate Nazis and TERFs.
