Robert E. Lee actually didn't care for the practice of slavery. Lee would have rathered the matter have been solved peacefully. He joined the Confederate Army because he couldn't fight against his family, friends, and home state. People actually had a sense of loyalty back then. Not all practioners of slavery were evil people. People comparing plantation owners to Nazis have their heads stuck in their own asses if they think executing 6 million people based on ethnicity is the same as American slavery.
He himself had slaves and there are reports that he treated them badly.
This is what he wrote in a letter I think it however a greater evil to the white man than to the black race, & while my feelings are strongly enlisted in behalf of the latter, my sympathies are more strong for the former. The blacks are immeasurably better off here than in Africa, morally, socially & physically. The painful discipline they are undergoing, is necessary for their instruction as a race, & I hope will prepare & lead them to better things. How long their subjugation may be necessary is known & ordered by a wise Merciful Providence. Their emancipation will sooner result from the mild & melting influence of Christianity, than the storms & tempests of fiery Controversy.
That is a reasonable viewpoint.
I don't mean to offend anyone, but some of the slaves came from societies that practiced cannibalism and lived like stone age people. You can't just make them adapt to modern life in five minutes.
Certainly there were people who treated their slaves like cattle and I believe they have found their places in Hell for their disgusting and atrocious behaviour.
But you can't tell me everyone mistreated their labourers. And you can't tell me they were better off in Africa where they got sold off into slavery to begin with (not by white people, either!).
The post I was replying to was saying Lee didn't care for the practice. He obviously did care for it and advocated it. ---
