Baloney. Between my years as an undergraduate, graduate student, and 28 years of teaching sociology (combined, well over 30 years in the social sciences), I've only encountered this idea of "critical race theory" (whatever that is) once in a textbook that only referenced the idea. Yes, there is a theory in sociology called Critical theory, but it's not the same theory.
So, in other words, NO< no one is teaching this mythical "critical race theory, at least in the social sciences. And, even is they are, so what? Does education threaten you THAT much?
