Slavery was wrong.......Disagree?
It's an interesting question.
Slavery has existed forever and still exists all over the world. Apparently it's part of the human condition, like war. Is war "wrong"? It's part of our species; there has never been a time it didn't happen, and never will be such a time. We do a lot of things that some people want to call wrong, but people just go on doing them, century after century.
War, slavery, rape, domestic abuse, robbery, embezzlement, buggery of children, torture, capital punishment....
Apparently all that and more is natural to humans.
I'm more interested in why the blacks let themselves be enslaved. Women for prostitution and blacks of both sexes for various work are currently the most enslaved populations. It must be because blacks are weaker, as women are. We know how it worked, that Gold Coast chieftains brought male slaves (mostly) in coffles, lines of completely naked men with their hands bound in a sort of wooden shoulder yoke, to the castle on the coast where they were embarked. The chieftains sold them for guns and gunpowder, mostly, and a few bolts of cloth. It was mostly guns and gunpowder and shot, however. Then they would go make war with these "modern"weapons and thus get more slaves to sell and so on.
Sounds to me like a black problem. Maybe they just shouldn't have sold each other to the white slavers. Nobody sold whites to blacks, never have, after all, except for white slavery of women as ever, of course, but that was and is still mostly to Arabs.
Maybe the blacks just shouldn't let themselves be enslaved!! Whites don't, we fight it tooth and nail. It's like the 6-million-dead-Jews problem. At some point, one starts to wonder, well, why didn't they fight back? Why just walk onto the cattle cars, you know?? Darn. At some point people need to stop getting on the slave ships, stop climbing into the cattle cars!!! You've got to fight for yourself.
I don't think it's very useful to call situations natural to the human race "wrong." The important thing is to keep from getting killed by them. Don't just lie down in front of the steamroller. Don't cooperate with the people trying to destroy you.
