the beauty of sexually reproducing species is that they have a gene pool to contribute to instead of being limited to cloning themselves. you should think of reproduction as a way to contribute your positive traits to the gene pool and for your negative traits to be removed.  for example, let's say you're very intelligent but you are ugly. when you have children, they will have disproportionate aspects of yourself and your children who have more of your intelligence and less of your ugliness will reproduce more than your children who have more of your ugliness than intelligence.  in this regard, you really shouldn't be concerned about race mixing or trying to keep the white race pure. what you should be concerned about instead is assimilating positive traits from whoever into your gene pool. this guy is supposed to have a phd in genetics, he should know this.
