However in the context of the morality of homosexual acts I need only resort to the natural law and biological complimentarity and duality of the sexes to argue that homosexual acts are immoral and contrary to the function of the sexual act.
you would first have to define what you mean by "natural law". then prove that there is such a thing as this "natural law" you just defined.
then you would have to prove that such a "natural law" actually condemns homosexuality.
would you care to?
