We shouldn't be too surprised about the rise of leftist racism. When you latch culture to skin color, it's kinda inevitable. When you latch behavior to skin color, you're gonna breed new KKK members. That's what we're doing in academia.
With cultural appropriation, we're teaching kids to "stay in their lanes." That there's white culture and black culture. This is pervasive enough that the Smithsonian bought into it.
What the fuck is white culture? What the fuck is American culture? Have you been to New York City? There are seven cultures that are metro accessible. You can drive through LA for a few miles and find a different culture. That's not to mention the differences between New York and Birmingham or some rural spot in Mississippi.
None of this has a damn thing to do with race.
Racists are the people who see a black person showing up late and think "Oh, that's just what black people do because it's their culture." That's the thinking of David Duke, diversity counsellors, and the Smithsonian. It's wrong and it's evil.
Treat people as...well...people. Individuals. Take people one at a time. That's liberalism. That's not being a racist. This bullshit that we're teaching kids is just producing more white hoods.
