Probably a combination of both.
The homes are saying “Do not act ‘white’.” The schools are saying “Yeah, be ‘black’.”
The school role is passive here.
The challenge for Christendom, from which probably the only meaningful salvation can come is to teach a non-racially-proud ethic. And this requires walking a tightrope because it is man’s fallen sin to be proud of himself. So much so that the results of my attempts to rebuke it are manifest. People want fundamental Christianity — but when push comes to shove, 95% of the time it is to hit their erring neighbors over the head with the bible. Not to draw them into a life that is so heavenly minded it is scoffed at by their proud fellows.
