Sure it was an aweful period in American history, but was it out of the ordinary? Civilizations have had slaves since the dawn of man (usually through the spoils of war). Even Africa actively participated in enslaving, and selling they're own people. Isn't paying an illegal alien chump change, modern day slavery? Sure most slaves were brought to America against thier will, but you should blame the ruling African elite of that time for profiting off of they're own people.
I end this with a question: Shouldn't African Americans point at least some of the blame on the people who allowed, and profited on the slave trade?
