An African-American guy who was a schoolmate a couple of years younger than me from elementary school through high school died recently. I don't know what the proximate cause of death was, though I know he had had a stroke a couple of years before and never quite recovered.
In any case, this post has drifted, let me try to bring it back to where it started. My point is this: though as an educated white male in the South I would have objectively appeared to be in a position of strength as a child, I was in fact hounded and driven by insecurities, and thereby pushed into a sort of war mode. I felt myself inferior to black guys on the basketball court, which was a huge proving ground. I wasn't particularly good at talking to anybody. So I probably isolated myself and didn't develop relationships with people at all, and black people in particular. So that now, objectively considered, my life continues to be segregated, certainly more so than I would like for it to be. And this trend has self-reinforcing tendencies unless I try hard to break free of it.
