Frankly, I think the people are uneducated, thinking they were the only slaves on the planet, by the only slaver, cracker whitey and not aware at all of cracker mo! The largest slaver of all man kinds history!
But then again, maybe they hit the dirt taking the get outta jail free card... as it is illegal for a muslim to enslave another muslim.
Some years ago the BBC did a comprehensive documentary about slavery and PBS would air it because it showed black Africans as slavers. Liberals never want them to face the truth. Remember the film "Amistad"? Spielberg didn't include at the end that Cinque himself became a slave trader after winning his freedom here.
