You mean the blond blue-eyed one? The one with proclivities for cystic fibrosis and osteoporosis and skin cancer? The one with the Kp(b-) blood antigen? Surely you weren't referring to the Aryan gene pool...

Culture is not genetic. Genetic diseases are, though. Lack of diversity in the gene pool leads to an epidemic of them. That is the biggest threat any gene pool can face, because it reduces the number of organisms that can successfully reproduce.

Ask any veteranarian which kind of dog has the most intelligence and the fewest health problems. The answer is the mutt.

Culture is transmitted by taught and learned behavior through a community to its children. If the community makes a space for all the people who live in it, the overall values of the community will be internalized and accepted by its members. If a culture treats some of its members, especially those grouped by arbitrary categories like height or skin color, as children of a lesser god, those members will go off and worship at the altar to which their "betters" have sent them, and the overarching themes of the greater community's culture may be lost to them. And they may be lost to the greater community too.

I find SPF 30 to be efficacious, and don't forget the UV filters on your sunglasses or you'll get cataracts when you're older.
