and so utterly wrong about others.

Exploitation and slavery are not the same thing, dude. Human beings being sold and treated like cattle is different from paying people dirt wages. And of course dirt wages are BECAUSE OF unregulated S&D, not because it's getting "swept under the rug." But the mechanism of how that works seems to forever elude you and I will NOT attempt to help you understand that again. I won't argue with someone who, metaphorically speaking, thinks gravity can be turned off and on.

There is considerable debate about the origins of racism. I think the Jews might have some disagreement with you on its post medieval origins. I'll agree the concepts of race and racism were more fine tuned later, expecially with the trans atlantic slave trade. But the idea of race in the Odyssey of Homer and the storytelling of “others” in Greek and Roman literature plays a large part in how they were represented in ancient discourse. If you go back much further homo sapiens largely killed off neanderthals, even though they were interbreedable. If that wasn't about race what was it about?

There is nothing specific about Christianity that prohibits slavery. To me the absolute proof that the bible is written by man and not inspired by god is that the 10 commandments, or anything else in the bible, doesn't forbid slavery. You can own human beings but you can't eat pork.
