This strikes me as one of the most blatant and heavy-handed attempts at a "just asking questions" tainted OP I've seen. Believe it or not, Oliver, most of us here know that most slaves brought to the USA from Africa were captured by other Africans and by Arab traders, and that the latter ran much of the wholesale market and commerce that transported the slaves to ports and sold them to the Europeans/Americans who shipped them into the USA. This has been taught in the USA schools since the 1960s as far as I recall.
The only surprise element to where this thread is intended to go is whether we are supposed to feel a loss of white guilt when Oliver helps us discover that the African slaves were already enslaved by other Africans, and therefore it wasn't "our" fault and we were actually helping those poor dark skinned people by providing them with better conditions than they had as slaves in Africa, or if we are supposed to learn that Muslims were once again the source of all evil. Perhaps our self-taught lesson was to be both.
I really do not wish to dwell much in a thread that was predicated as an insult to my intelligence and knowledge, but I will just ask Oliver to himself consider a few points before he continues this thread: How many people would have been captured and transported as slaves in the first place if the USA did not provide a huge market for them? How many Europeans and Americans (particularly New Englanders) played a direct role in the slave market by owning and running the slave ships that brought these people (under horrible conditions) to the USA and how many slaves died en route? How many Americans arranged and ran the slave markets that sold these people as property, often ripping apart families, once they reached the USA? How many people ended up enslaved from birth once slavery was firmly established in the USA, making the import of new slaves from Africa less necessary for the "strange institution" to be self-sustaining? I will not even go into all the abuse of slavery itself.
Oliver- a hint for the next time you try a "JAQ" foray: Your "Given the lack of information available online, it seems as if that question isn't much of an issue for some strange reason." was a dead giveaway. Lack of information? Ha! I've seen children's books with this information in them!
