Silence is violence when there's a concerted effort to normalize unjustified hierarchy through cultural peer pressure. Whether it's 'let's all make rape jokes, also rapists aren't actually bad', or 'let's put up statues of slavers waaaaay after the war they were in, because slavers aren't actually bad', part of the purpose of such social pressure is to stifle anybody who's inclined to object.

The intensity with which people demand their right to performatively line up with bad things they claim they are not, right then, themselves, actually doing, tells me something about those people. I'm deeply not interested in exploring hypotheticals through which people might claim they want to dress up as a Nazi without actually being one, and deeply not impressed with the argument, "You're cruelly trying to punish me for BEING a Nazi, but I am only DRESSED as one, so you're morally obligated to be silent and let me do my own thing!"
