Is race-mixing a form of natural selection?

Question

The worst Anglo-Saxons always seem to breed with the ne-gro, the lowest race one earth. I wonder if this is nature's way of taking the worst of our race away from us, a role that war played in the past.

I'm not saying it's a good thing, it's terrible, in fact, but it happens.

Answer 1

I don't think personal preference is a form of natural selection.

Answer 2

you're a bit dense really  

Answer 3

Definately not, People who actaully know stuff about science would also know that if we were to compare human evolution then Black people are more evolved then white.
