I nearly always just keep my mouth shut because I know that I can be shot down and 'discredited' purely because I'm white, male, and straight. Part of it is perhaps age (I'm 31 now, and less angry/opinionated than I once was), but it's mostly just that I have, in the past, been repeatedly disregarded or outright abused because of who I am rather than what I'm saying. That kind of response is fundamentally censorious, and it has worked; I'm effectively self-censoring now to comply with the wishes/intentions of this lunatic fringe. From your comment, I get the impression you're doing the same.

The scary outcome of that is a continued chokehold on the narrative and conversation by these extreme fringes, and no change for the better because nobody is willing or able to engage in a reasonable discussion or take reasonable action.
