No disagreement, and I was probably racist back then. I'm just agreeing with an earlier comment that some of the 1950s authors were not "well adjusted", because I now think of racism as a sin.
I think we'll only approach an equilibrium on racism if and when we reach consensus that it's innate human nature to be prejudiced, and that what distinguishes us is whether we make an effort to counter our base impulses.
Let me join you in acknowledging that I have been racist before. (And I might be again, if I slip up.)
