Billboard proclaims "Nobody is born gay"

[DeistPaladin]

Your request is simple enough since 1) I have no prejudice against homosexuals as human beings ...

...and I'm guessing you'll tell me you have gay friends, right?

and 2) my position has rational support.

Anyone, other than ontological naturalists, can see that things are partially defined by their natural functions. Living things are, by their nature, directed toward the things that allow them to sustain life and thrive. For example, the heart is directed toward pumping blood.

Likewise, it is a biological fact that for the human race to exist it must reproduce and that is the natural purpose of the genitalia, i.e. to get semen from the penis into the vagina. The pleasure of copulation and the inordinate strength of the sexual appetites serve to motivate people toward productive union.

Now because human infants are not self-sufficient for years, conjugal love also serves the purpose of strengthening the bond between parents to sustain the children that depend on the family for their mental and material support. These are biological facts.

That people pursue sexual pleasure without consciously thinking about procreation is of no consequence. All that matters is that it is directed toward its proper and natural end. There is nothing inherently wrong with kissing, petting and oral/genital contact to the extent that it increases arousal in preparation for intercourse. Unlike these, the possible transfer of feces and harmful bacteria make sodomy an unsuitable preparation for vaginal intercourse. In addition the structure of the anus made for defecation and is not a suitable receptacle for any foreign object.

People both homosexual and heterosexual engage in practices that go contrary to the function of sexuality and in so doing thwart the natural good.

As one who is bisexual, I can tell you there is nothing different between same or opposite gender attractions. On an emotional level, everything from falling in love, the rush during sex, the feelings of jealousy and the pain of heartbreak are all the same experience. The only difference between same vs. opposite gender relationships are some distinctions with body parts and the physical mechanics, which, though you spend a long winded several paragraphs obsessing over, are not much more than a variation on a theme.

The natural purpose to homosexuality is discussed in detail by biologists much smarter and more qualified to discuss the subject than you. As much as you put on a pompous demeanor to try to mask your bigotry, i suspect you have zero qualifications on the subject and have done no research whatsoever. Am I right?

One such purpose discussed by actual scholars who have done real research is the creation of couples that adopt children who have lost their heterosexual parents for whatever reason. We see such adoption take place in both the wild among animals as well as in human society where it is allowed. Since children are orphaned through either death or abandonment and since heterosexuals want to have their own children, the existence of gay couples is beneficial to society.

Now were I to look at human sexuality from a bigoted perspective similar to yours but biased toward my own bisexuality, I would view strict heterosexuality and homosexuality as a "defect" similar to partial color-blindness. There are those who can see some colors but others appear as shades of gray. "What a pity that straights and gays can only appreciate the beauty and sex appeal of one gender and how they might be missing out by limited their options to find a good partner and can this be cured, I wonder..." or such might be the prevailing attitude if society were dominated by a majority of bisexuals who adopted such bigotry.

This is not my view. People's taste in partners are what they are and its their business provided none are harmed. I merely present such hypothetical bigotry to provide a shoe-on-the-other-foot reference for you.
