By "sound assessment" you mean any information that is not your personal opinion...an opinion that needs to leave out information to attempt to sound remotely correct yet making you a bigger idiot like saying "the 1.25 million number" is smaller knowing damn well that it only represents the slaves they kept to support themselves which was a fraction of what they sold through-out Islam because it was a main source of income for them to do so.
Also, who said ANYTHING about Aztecs, Maya, Inca or any other natives of the Americas? That was a massive goalpost move attempt there to cover your previous idiotic comments. There can be no information about native slavery before European contact since they were so barbaric they didnt even have a written language to write it...but we DO know that the so called 5 civilized Native American tribes had both black and white slaves even after the civil war...as actor Don Cheadle found out the hard way all while still acting as if only white people ever had slaves...
Lastly, Tripoli...Lybia...AKA, North Africa...idiot...trying to call the Barbars on the Ottomans shows you know shit about fuck-all as usual.
