As an aside, I wouldn't overstress the "Confederate" part of your description. Yes, overt racism in the South was much more pronounced when I was a boy there, and we were frequently reminded of it by commentators, particularly in the North.
Oddly though, when I got older and traveled, I found it with a different flavor, perhaps more bitter in the North; more bitter, because the practitioners were in an odd denial.
People who would admit to me that Blacks, Italians, or Irish, weren't "allowed" in one neighborhood or another, with an implied suggestion that they might be killed if they “trespassed,” still assured me that Racism was a wholly Southern condition.
“Beams and motes,” of course.
