Is the argument presented not that homosexuality is self defeating? You cannot exist in a purely homosexual society because there is no procreation without heterosexual sex. Homosexuality cannot perpetuate itself, for lack of a better term. Homosexuality can only exist within a heterosexual society, and would cease to exist without it. Therefore homosexuality is unnatural because it is non productive.
