The fact that white people hated the civil rights movement so much they actually rioted (often harnessing that anger on school busing programs) has been completely memory holed and we all just sorta pretend like it never happened. Even as someone who likes to read history, I don’t really know all that much about it. But I assume it never gets brought up in history class or society at large because it spoils the narrative of “MLK Jr gave a speech, we passed a law, and now we have total equality and racism had been defeated”.
