It seems like you are criticizing the most radical interpretations though, which is fair but not very representative. Of course someone can take CRT and use it to justify ethnostates, racial superiority, etc... But at it’s core CRT isn’t those things. It would like looking at academics who used Darwinism to justify eugenics and say that the theory is rotten.
Also, CRT being about righting wrongs is about fighting racism. That isn’t a particularly controversial wrong to right. Don’t get me wrong though, since CRT is in the limelight so much these days, there are a bunch of idiots, like Robin D’Angelo, who get a platform and are able to spread harmful ideas. I expect this to pass, since there are many on the left who seeing the shit she is doing and rejecting it.
