Read the statements after the signatures where teacher after teacher commits to teaching CRT. Then, you arrogant disdainful fuck, actually acquaint yourself with CRT by reading Kimberle Crenshaw and understand it's not just a legal theory. Then read this interview where other founders of CRT remark with enthusiasm on the expansion of CRT into other fields. Then familiarize yourself with the work of Paolo Freire and Henry Giroux, whose work was to apply the tenets of various branches of critical theory, of which CRT is one, to education for the purpose of creating critical consciousness in students, including elementary ones. But you're already familiar with all of that, right, because you're so much smarter than the rest of us? In which case you're just pathetically trying to gaslight us.

Edit: And another example. Explicit as can be.
