where our kids go its all about civil rights. its all they learn about. every book my 5th grader read was about a "person of color" written by a person of color. every book is about overcoming racism in some form. my kid didnt learn about presidents, she learned about martin luther king and ruby bridges and rosa parks. she doesnt learn about the declaration of independence, she learns about the civil rights act. washington isnt the first president, he's a slaveholder.
all of which are true. and its a different perspective from which to view american history.
do they teach "crt"? no, but they do the bastardized version of it for grade school kids: "black and brown kids are constantly discriminated against by white people." "crt" is a theory about societal discrimination that requires thoughtful debate, you get the HR friendly simplistic stuff fallout from that in grade school and middle school.
i think there are plusses to teaching it that way and minuses. like everything else. but it certainly "exists" in schools, even if it doesnt exist to the extent tucker carlson would have you believe.
