Unless I am mistaken, black tribes in Africa enslaved other tribal members and sold them to the white slave traders. In addition, if you look carefully, the muslims were and have always been involved even to this day in slave trade. So get off you pity pot and live the life given to you by God Almighty in this still free country.
When I remind my students that there was slavery before the slave trade that came to America, they look stunned, as if something has been kept from them.
