You wrote a great deal, and I'm only going to respond to the one point that right wingers can use against us. No, CRT is not taught in any K-12 school in the US. It is not a curriculum. It is a method of examining US laws. Few teachers at the level would have the knowledge to import it, and few students have enough historical or legal knowledge to engage in it. When we talk about things, we have to get them right.
