Have you seen the new World History text, printed and published by the "Buttocks, Texa$$ Dept. of Ejakayshun"?  Therein you'll find that Native North Americans invaded Europe, drove the indigenous white folks off their lands and killed 'em by the millions.  Almost immediately after that west Africans invaded from the south, rounded up the survivors and sold 'em to the AY-rabs, who burned whoever wouldn't convert to Islam at the stake, except for the pretty white girls.  Word has it the Jews were in on that action, too.  Apparently they'd cornered the firewood market.
