Again - CRT, CT, gender theory, pragmatism, behaviorism, etc are all pedagogical theories related to teaching.
Prospective teachers learn these theories in university and apply lessons learned from each in order to teach their pupils as they see fit.
Pupils are not being taught CRT. They're not being taught constructivism. ETC
Another example of obfuscation - one side screaming this, that, and the other thing are CRT - when they clearly are not.
