If you love someone then who really cares. Too many times people give up the one's they truly love because its not the social "norm" and then 10 years later they are getting divorced from the "right" person after having numerous extra-marital affairs. Interracial dating leads to genetic diversity which in turn propagates the human race. Ashkanazi jews (jewish people of european descent) who have children together are 100 times more likely to have a child with tay sachs disease who doesn't live to be 2 years old. Is that there fault...no it was the fault of a psychotic dictator who thought the killing of 6 million people would benefit the world and instead created a genetic bottleneck. Should they date outside their "race" probably or at least they should get genetic counseling before they even have children. Other genetic disorders such as sickle cell anemia are found only in those of african descent because the sickle trait actually causes individuals in living situations where they are exposed to malaria to be less likely to contract the disease. Mixing an individual with sickle trait and a person from non-african descent will all but eliminate the possibility they will develop sickle cell anemia. I happen to be white of european descent and my wife is black of african descent. She has a thalassemia trait which appears to be anemia to those not looking for it but I know that my kids (she's pregnant with our first) will never be in danger because of the autosomal recessive qualities of the disease. All in all genetic diversity is a good thing, but if you don't want risk upsetting the social "norms" I really couldn't care less.
