I like what you said, but I have to admit that it seems like all white people in the 50's were actively racist. Showing up to lynchings, keeping black kids out of school, government institutions barring black families from moving to suburbs. Where do you draw the line between "understandable," "reasonable" racism and bigoted assholes? At what point do they take responsibility for their actions? Verbal violence? Physical violence? Imprisonment? Murder?
