Evidently US-born-and-raised blacks have not been told:
* A very high percentage of blacks taken as slaves went to Muslim kingdoms (or whatever they were called in Arabic and Turkish), not to the Western Hemisphere.
* The two most significant sources selling slaves that went to the Western Hemisphere were neighboring African tribes and Arab slave traders.
Knowing those very basic facts might make Aisha, the name of Mohammed's wife (the one "married" to him when she was age ~6), a bit less popular as a name for black girls.
