This is why gay youth commit suicide at a rate of about seven times that of straight youth. It's not natural. Well, that's probably the weakest argument of all, since biologists frequently see homosexual behavior in other animal species, and in livestock ranching, homosexual behavior is so common it is considered a problem. Homosexual behaviors have been noted in every primate species so far studied, and in man's closest living relatives, the bonobo chimpanzees, bisexual behavior is universal. Among humans, homosexuality is found in all cultures and with about the same frequency it is found in America.
Cultural norms seem to have little influence on the incidence of homosexual behavior.
So the claim that it isn't natural becomes rather difficult to support. It's a perversion. And being essentially a religious argument, it has little place in a society that believes in the separation of the powers of church and state. It's against God's law. Well, of course this is a purely religious argument, and it presumes that the homosexual is or should be bound by the religious principles that are propounded here by the religionist.
