You do know that black people owned slaves in this country back then as well, correct? Go look up who the largest slave owner in South Carolina was at the onset of the Civil war. Also, a number of black people fought willingly for the Confederacy Just wanting to make sure you knew your history before trying to impose White Guilt on everyone.
If you are so concerned about slavery then start calling your congressman and the White House and demand that something be done about slave trafficking in Libya. There are open slave markets there now where African are being sold for about $200 a pop.......by Muslims. You know, the barbarians stuck in the 7th century.
