My favorite diversity is not the politically correct set-piece photo arrangements that universities, businesses, and others carefully assemble for image purposes. Rather it involves people freely choosing spouses and partners across "racial" lines because they are color-blind and more interested in the contents of the partner's character.
The March 19 NY Times includes "Black and White and Married in the Deep South: A Shifting Image". This may be better than even Martin Luther King had dared to dream.
I am old enough to have seen the old South and am always happy to see good news like this. We will never resolve differences of opinion on whether the changes we see are remarkably swift or too slow. Perhaps it helps to note that tribalism is as old as humanity and seeing it recede in our lifetimes is nothing but good news.
