Israelis would vote Trump if they oculd vote in our election, but ya know,
the rest of the world hate him.
Dion only knows enough history to exploit people's ignorance. There were some 10 million Africans brought to the Americas during the trans-Atlantic slave trade, only ~300k of whom were brought here. They of course practiced hereditary slavery there too, but the reason for such the great disparity in numbers is that they didn't treat them well enough for them to survive as long, just kept importing replacements.
And the Arabs had black African slaves too. They didn't do hereditary slavery as practiced in the AMeircas because their slaves were eunuchs; they castrated or bought them already castrated from African warlords and merchants while the female slaves were primarily used as concubines.
