Jon Rowe has an interesting post about the question of whether homosexuality has genetic origins, and whether it matters. I’ve always been of two minds on this issue. On the one hand, I think the evidence is clear that homosexuality is a genetic predisposition, like any number of other traits, most of the time. On the other hand, I don’t really care. Even if it’s not genetic and is entirely a matter of personal choice, it is no less deserving of equal protection under the law.
