I am in my 80s and I cannot tell you how many times I have been told that very same thing. I will believe it when I see it.
I am very close to 90 years of age as a WWII overseas vet and I tend to think you have it right. All thoughts that somehow/sometime the black peoples vote will go to what the white population has built is wishful prognosticating. When I was a young boy I never had any problems living and playing with ‘black’ youths. We even liked being on a team with ‘black’ youths because they were among the best of players even back then. For years in my youth we lived in a house that was next to the residence and church of the towns ‘black’ pastor. My brother and I were both invited to the pastor’s house the day his wife gave birth to their second child. I’ll never forget the experience and awe of seeing a newborn baby for that wonderful family. I often wonder/muse about how the US society has changed to make such changes of attitudes.
