@karchie i’m not a great fan of Popper’s Paradox of Tolerance, because I think in practice once we accept it we have no principled grounds for line drawing. the same case for free speech broadly (we might be wrong!) should chasten us in imagining we can identify meritless intolerance.
but putting that aside, at least invoking the PoT is an open and principled way of acknowledging that sometimes we do mean to suppress things, and that what we are objecting to is bad criteria for doing so.
