This is exactly why it's exhausting. This type of thinking necessitates everything being taken as a zero-sum declaration on extremist viewpoints. "You must denounce X, Y & Z at every opportunity or you are a de facto nazi." Denouncing happens constantly. The people who most need to listen generally don't, they just stay in their own curated feed.
It's okay to make space for yourself in the world as you, not as a political subject, not as a locus of oppression, not as a body inscribed by the discourse of socially constructed identity. Because if you don't, you're essentially making a declaration that you not only have no existence apart from it, but that you are ultimately a puppet obliged to stand up and dance every time Trump or yet another alt-righter vents their life frustrations by saying something obnoxious on the internet. That ultimately they control your thoughts, feelings and time, not you. TBH it's important to just tell all that to eff off every once in a while, and just be a person who wants to talk about Salt & Sanctuary or whatever. It's alright to create a place to facilitate that.
But beyond all of this, given the fact that only
32% of millennials and Gen Z are republican or even republican leaning, I don't think the notion that "shut up and kill the browns," as you put it, is the default viewpoint in gaming circles is supportable. It's just that the losers who say that sort of thing are loud and routinely use bots to fill the vacuum of their lack of actual allies.
I mean, I kind of said that when talking about smuggling in retrograde views under a cover of false objectivity. I will admit to not wasting my time following his exploits to know it all in detail though.
