content: Outside of genocide? I can't think of one.  You could take the reparations route, with revoking citizenship and giving them money and a one way ticket. The problem is that there are plenty of them who aren't fucking retarded. So now you've got say 5% of the blacks left over, and there's no way in hell they'll ever leave. And when they have kids, not all of their kids are going to have the genius level IQ's that they posses. See Will Smith and his retarded children. So now  we didn't really do anything except buy people time, and in another 300 years we'll be right back to where we are today.  Africa is too much of a shithole for anyone (who isn't a complete moron) to be willing to move there.
