Because they can.

Because African America is a fucking shit hole.

The native culture of African America is completely self destructive and any sane person who can get away from it will.

Because black men are so consumed with imitating street thug rappers that they are completely worthless, and even dangerous to be around.

It's the same reason I've only ever dated white chicks, and why my wife is white. If you want out of African America, you won't have a black partner.
