Crackpot theory #1:
Slavery was revenge for the Moorish occupation. In college when I learned that the Moors controlled Spain from 711-1492 A.D. but, then right as they kicked these cats out, this same country leads an expedition to the New World that same literal year (1492) and then began to scavenge the same coast of Africa where the Moors were from to get their slaves
Maybe they went a bit further down from Morocco/Western Sahara but, it was the same general region
You kick out people that used to rule you for a millennia, then you get slaves from the same region of the world they were from
Crackpot theory #2:
The (white) powers that be know the Egyptians and the Moors were black or had a large, large black component. But they choose to gaslight to maintain the conspiracy that is White Supremacy. They have innumerable amounts of mummies but, only a handful have been tested with a good amount of them coming back with E1B Haplos. If there were no secrets, they'd test every single one and be as transparent as possible but, they're not. That tells me they don't want the public to know. I know there's some rooms or files we don't have access to that only a small percentage of people on this planet do that confirms this stuff.
