You know full well why no one in NC has ever been taught about the Wilmington massacre. As to your "so many racial atrocities" comment, that's disingenuous....how about we start with the very worst atrocities? Like the Wilmington massacre and the Tulsa massacre? Think we might be able to do that?
And that "shouldn't be a teacher" line? Nobody is naive enough to think that no white parent would go to the school and claim their precious offspring was made to feel uncomfortable when he or she heard that elected black officials were murdered in the streets by white terrorists however it was taught.
