They didn’t go anywhere near it in 80s NJ education. Brief mention of “race riots” in Newark, late 1960s and a vague “guys with white hats did bad things 100 years ago but we’re past that now”. Then again, my 6th grade history book in 1983 was from 1958 and showed blond haired white cavemen without beards so…
not all white Republicans wear white hats. Once upon a time there was a type of Republican that would today be indistinguishable from an average Democrat or even Progressive. But they dwindled away.
