Tone puts out a lot of good info, but stating Africans sold other Africans into slavery misstates history. The trans Atlantic slave trade was wholly a white creation, African countries/tribes "participated" under duress. If African countries are guilty of slavery, then us blacks here are guilty of allowing black men to die at the hands of racists. There was no quid pro quo wealth transfer either. White people came, conquered, stole, and colonized. End of story.
Uh WRONG.
