Dressing well, being polite, and liking individualism is apparently white supremacy, along with almost literally everything else. Mozart is racist, cars are racist, milk is racist, education is racist, smiling is SUPER racist.
It's not about the supremacy, it's about the culture. Lefties hate western culture, so they mask their own racism for white people by calling it "white supremacy".
I don't know who needed to hear this, but it just clicked for me all of a sudden: replace "white supremacy" with "white culture" and you lift the mask.
Oh yeah. It's a slow burn. They realized the class warfare rhetoric didn't work in the US (there's too much upward mobility), and the only way to get their "Marxist utopia" was to undermine it from within. The Frankfurt school certainly accelerated it. Our culture is fragile and few realize how thin the veneer of civilization is. I hope we fight to save it. I'll check out the book. Thanks for the recommendation!
