Concepts advanced by CRT--race relations as oppression, focus on intersectional identity, heavy weighting of narrative--are in K-12 curricula.
If you don't want to call it CRT, come up with some other label. "Anti-racism" isn't good enough, because there are other ways to do anti-racism (team-building exercises, focus on excellence in a diverse group of people, focus on empathy for the individual regardless of identity).
