He is certainly right about one thing. There were black Confederate soldiers. Even Ken Burns showed such photos, and that must have hurt him sincerely to have to show such a thing.
In seems to me I read somewhere that there were free blacks who owned slaves in those days. I'd have to search my archives, but I suppose if I found such to be true I would be considered revisionist.
You have to verify, but I think She was the daughter of a white plantation owner. Her two all white half brothers sued and lost in court to take over her inheritance.
New Orleans had a lot of black slave owners.
Start by reading up on the history of antebellum New Orleans.
Some of the most wealthy residents of that city were slave holding blacks. Some of the most wealthy were people who were major players and partners in the slave trade, including illegal smuggling after 1808.
These people were not race traitors, motivated by ideology. They were motivated by greed and profits just like their white counterparts. Many came from areas of Africa where slave trading had been a way of life for generations.
Many of them justified the trade because (1)the alternative was being killed as an enemy and (2)it gave them a new opportunity in a new land.
You might also want to read the history of Liberia, a country founded by freed slaves from America. One of the first things they did was to go out and press enemy captives into slavery to work on their own plantations.
Long story short is that white people have enslaved each other for generations. Indeed our liberal rulers want the same things for we, the peasant class, today. Are black people so morally superior that they would do something different? If you believe that, just look at how the members of the black ruling class treat their own people in America today.
