I don't see the difference coming from past experience in slavery. I see it coming from Hollywood. When I see old TV shows and movies with black actors in them, prior to the 1970's, there was no difference in the way those characters walked, talked, dressed or behaved - unless they were showing a characature, like a slave ("Yazza Mazza"). That all changed in the 1970's when Hollywood created the TV show "Good Times", with Jimmy "Dynomite" Walker. His parents and siblings did not walk or talk any different from any other white characters/families, but the one son did. Since then, depicting blacks as different has expanded. To their detriment. I hope they choose someday to not let Hollywood diminish them and dictate their fate.
