What are we calling right-wing idpol? Isn't that white supremacist stuff? Seems like people are always calling that out.
There's a reason why "The Party of a God-fearing Christian" used to be a meme. Hell, Reps and other reactionary parties have always tried to persuade the lowest of white men were still better than the best of colored men. Martin Luther King has quoted such a phenomenon, and I've seen it in my own country, where it might be not a race-focused issue, but it basically can be summed up as, "Vote for Putin/UR, and he'll keep you safe from the evil NATO/EU."
"If you can convince the lowest white man he's better than the best colored man, he won't notice you're picking his pocket. Hell, give him somebody to look down on, and he'll empty his pockets for you."
Also, I'm pretty sure a lot of "Not-Nazis" were very angry about Wolfenstein 2 and it's "anti-white agenda"*. It even featured a black woman in a major role, which only fed the reactionary rage further.
* With the whole message of the game basically being, "Nazis are bad".
