Black Americans descend from slaves that were sold by black chieftains in sub-Saharan African to slave traders in exchange for a few cigars or shiny beads. They were the dumbest and most useless of their clan even back then, which is why they were dispensed with. What do you expect from these people a few genrations later? Some of their women got fucked by horny white autists and that's why you have a few somewhat acceptable ones, but overall it's a tragedy. The slave ship merchants (Jews) did this.
