Dear Coquette,

My friend’s Southern father told me that being gay is not at all biological because it’s “classified as a mental disorder” (seriously?), an “unnatural genetic mutation” and asked: If we teach kids about homosexuality, why not teach them about polygamy and…

In case you do want an argument or two though:

Twin studies have shown that homosexuality cannot be purely genetic. However, even if it is hereditary, a homosexual would increase the reproductive fitness of his or her gene line by helping take care of the family’s children. They would not expend additional resources with accidental pregnancies. And there really is no such thing as an “unnatural genetic mutation”.

If homosexuality were hereditary and negatively impacted the reproductive fitness of the gene line, it would be gradually be selected against and removed from the gene pool, and that has clearly not happened yet (surveys suggest that most cities are at least 1 to 15 percent gay or bisexual), unless it is caused by a relatively recent genetic mutation. Since homosexuality is present in animals other than humans, the trait has either existed since the common ancestor of nearly 1500 species, or emerged independently in each of them, lending more credence to the argument that homosexuality is beneficial to a specific gene line.

Throw evolution at them, I hear it makes ‘em angry :)
