I didn't say you DID say that Africans tried to enslave Europeans. But the claim "the primary slavers were black Africans enslaving other black Africans" is factually WRONG. Africans HELPED enslave their own, but the entire impetus for slavery was European. They created a vast market for slaves which they themselves helped fill - with troops, ships, and money to encourage Arab and African slavers.

WHO is ignorant of history, David?

You're partially correct about Asians and Europe, and yet, Europe was never permanently enslaved, destroyed, or even seriously damaged, and it STILL became the master of the rest of the world, imposing its will on ALL other continents in later years.

Nor did Mongols suck all the gold, silver, and oil out of the lands they (temporarily) conquered.

Still need some confirmation of your claim that I'm "logically challenged," too. That made no real sense.
