No one is asking you to self-flagellate. You're white. That gives you things for free that POCs, and in particular Black people, have to work harder to receive (and I'm not Black). It also HAS created a system that benefits white people not only at much greater levels than all POCs, but extrinsically--that is, often NOT on the basis of merit ---at the decided expense of POC success. You should be admitting it, so that you can decide how to temper that massive privilege in a way that doesn't crush everybody else. That's called morality, and if you call yourself a Christian, you should consider obtaining some.
I agree with you on one count: there aren't two truths here. There's one: America was baked on the kiln of white supremacy. White people get more with less effort and often with lower performance. It's time to pull out the moral basket and pick out at least one. Anything more than the shitshow we've been subjected to, worldwide, for 500 years and counting.
That's reality. You can take it any way you like, but your idea of untermenschen won't last forever and is already out the door. The rest of us will be equal to you ubermensch eventually whether or not you like it.
