Almost all slaves sold for Western Hemisphere slavery were rounded up and first vended by African blacks.
Exactly correct. The blacks practiced slavery in Africa long before the white man. The white man in Europe practiced slavery historically in Europe. Those slaves were white, black and Middle Eastern. The Muslims practiced slavery also and in some places it still exists. The Muslims had black slaves, white slaves and Middle Eastern Slaves. Slavery was and is an evil practiced by all races, religions, and cultures. IT IS NOT THE WHITE MANS GUILT. It is the guilt of all humanity. I worked in Nigeria out of a port called Escravos. That is Portuguese for slave. It was a slave port and trading port in times past. English, Dutch, American, and Portuguese ships called at this port to buy slaves from black Africans. As mentioned it is not "The White Mans Guilt." It is the guilt of all society during those times.
