Quite so. I found several letters written home to New England by soldiers who drew a clear line between northern blacks and southern blacks. The difference IMO is the difference in experience. Those in the north had responsibilities as well as the dignity of earning a living (underpaid though it might have been) while those in the south lived through an enforced perpetual childhood.Which is not an unreasonable belief. Someone who has spent their entire life denied education while experiencing a variety of traumas (physical and psychological abuse, rape, suddenly and forcibly being parted from your spouse and/or children) from a young age through adulthood is unlikely to ever be a fully functional adult.
