> If we can't debate against nazism or slavery and win in the eyes of the audience, on democratic terms, I guess it is to late to be "intolerant of intolerance" and democracy has already failed. Probably, yes. Democracy is bad at edge cases (Hitler was democratically elected) and undemocratic means must sometimes be used. Deplatforming is pretty mild as far as undemocratic means go. Such is life.
