CRT seems to me like a medication with a statistically significant effect size and a lot of side effects. But here's the thing...doctors prescribe that kind of medication every day. That's standard practice. If you don't like it, come up with a better medication.
Our nation is at a point where we need to focus on consolidating our nationhood and making sure Americans feel like they own America. I heavily doubt CRT is the best way of doing that, but...find me a better way, or CRT is what it's gonna be.
The last people to actually try hard to unite our whole country in a unified national identity were the New Deal liberals. They succeeded somewhat for a while and then it fell apart. Are we up for another try at that?
