It's invisible, but all-pervasive. White people can't see it because they're inherently racist. It can't be measured in terms of demographics because the demographics are invented by white people. Anecdotal evidence from white people is disqualified because, well, they're white.
I'm not making any of this up. See Critical Race Theory for a real eye-opener.
The way this is set up is quite clever. There is literally no avenue left open for criticism that is not itself a function of the model. It's perfectly circular. This would be laughed out of any class in formal philosophy as being completely untestable but, then, those places are ridden with racism, aren't they?
It is, essentially, a twisted form of Original Sin with no chance of redemption, ever. It is astonishing how seriously its proponents take it, and worse, how seriously they insist that everyone else take it. They're building curricula around it. They're indoctrinating students with it. They're poisoning society with it.
The weakness of Critical Race Theory and its associated academic edifices is that they rely on a desire for fairness by the whites of Western Civilization.
What happens if white folk decide “screw it, you people are no longer worthy of our concern”?
