Everyday on the internet I see White people threatened, disrespected, or legislated out of existence... then the ensuing backlash in which people try to reassert the rights of White people... and then the backlash to the backlash is always "these neo-Nazi cons trying to cancel us are the real gulag runners". It's exhausting. Infuriating.
Some speech suppresses the speech of others. And some people don't want to be taught that they are hateful. If you make declarative statements that villainize majority groups, you make others fear for their safety and it silences voices. That is a form of "violent speech", though that term sucks. Free speech isn't just about saying anything you want, it's also about maximizing the number of voices at the table, and to do that you can't just let people get away with saying vile shit.
