It is core doctrine of pro-gay orthodoxy that homosexuals are born gay. Though science has yet failed to affirm or deny this, the vast majority of gays and their supporters are convinced of it. Sexual orientation is seen as something discovered, not chosen. Instead of debating the merit of this assertion, let’s grant the premise that sexual orientation is determined prior to birth by genetic, gestational or other factors. The question is whether any valid conclusions flow from this. I don’t think so.

Error 1: Sexual orientation cannot change

If present at birth, sexual orientation could come from either biology or psychology. If biological, then a medical procedure may be discovered to alter it. Science gushes with the ability to change things we were born with, especially conditions which past generations considered permanent. We can treat genetic diseases, repair cleft palates, perform height-enhancing surgeries and even perform sex-change operations.

Similarly, if the issue is psychological, treatments may be possible. Many traits and behavioral patterns people believe ought or need to be changed can be adjusted by good counseling or psychopharmacology. Simple induction concludes that if medicine goes looking for a treatment for homosexuality, it might find one.

Many gays will be outraged at this line of reasoning. But why? We’ve been told that homosexuality can’t be a choice—apparently because so few would choose it. Clearly some gays would relish the power to turn their unwanted condition into an optional one. And why shouldn’t other gays be happy for those who would then be truly free to choose? After all, they’re happy for sex-change operations, which make it possible for transgender persons to undo the birth nature they think was mistakenly given them. How can gender be so fixably wrong but sexual orientation so unfixably right?

Error 2: I have no choice about how I behave

There are two kinds of inborn behavioral tendencies: the resistible and the irresistible. Unless we are supposed to believe that homosexuality is so involuntary that every gay sex act is literally a matter of biological determinism, we are left with the more plausible alternative: the desire to have gay sex does not compel anyone to actually ever have gay sex. One may not be able to control who attracts him, but he can certainly control who he has sex with. Consider the non sequitur of a gay man offering to explain last night’s particular sexual encounter by saying, “Well, I was born gay, you know.”

Free will is precisely the capacity to resist a carnal urge. If a gay person can refrain from sex even once, he has shown such free will. Thus, sexual choices devolve to him, not to his inborn disposition. Of course, straight people and gay people alike deny their sexual impulses all the time.

Error 3: If I was born gay, then acting upon it must be good

No one denies that gays have strong desires to be sexual with like-minded, like-bodied others. But strong desires do not justify behavior. Otherwise the study of ethics would be nothing more than the articulation of our impulses.

Some men may be born promiscuous (and perhaps most are), but this doesn’t legitimize adultery (or polygamy, for that matter). Since morality involves precisely the question of which desires are good to act upon, gay behavior cannot be justified merely on the grounds of experienced gay desire. Continued...
