The south used blacks for slaves.
Well lets face it between our evil slavers and black evil slavers who sold them to us its not like there were a lot of engineers or professionals in the tribes.
America couldn't turn them loose to fend for themselves. All they knew how to do was labor at the time.
It takes time for all humans to civilize look at the ignorant serfs who came from England,Ireland and Scandinavian nations. We also were treated bad. Although blacks were treated worse and it was because of the color of their skin. Humans are tribal and like those who they favor facts of life and nobodys fault. But their culture also had something to do with it too.
Africa wasn't exactly a thriving metropolatin nation for 5000 years because of culture. Look at America when it was discovered,not so metro either.
Look at the face of a man when told his child looks just like him,why is that? That sledom happens when the child is mixed race, especially black race has some real dominant genes.
Why is it blacks can say " black is beautiful, but whites can't say it without being racist? Imagine a white man standing in around of blacks saying " white is beautiful". We are doing better or were till they started dividing us. We are working on accepting each other in many ways hope its not too late to save our nation.
