Okay. I've had some time to investigate. The original post is based on a lie at worst, faulty data at best, and-most likely-predetermined outcomes based on a religiously driven agenda.
You see, there are a number of twin studies on sexuality. In one, 52% of monozygotic male twins shared sexuality, but only 22% of the dizygotic (two eggs....) did.Most studies have shown similar results, with a higher incidence of shared sexuality in the monozygotic (what the OP calls "genetically identical") twins, indicating at least a partial genetic basis in sexuality, which is, as others have pointed out, not merely a biological behavior in humans (or other primates!) which is used in a variety of contexts, and far more fluid than simply genetics.
For myself, I know that at a very early age, while I had no idea what it was, there was something I wanted to do with girls. Other men have said the same thing, and-among my homosexual friends and relatives, many have said something to the effect of having similar early attractions toward boys. While this is anecdotal, it lead me to believe long ago that such drives,whether typical or, as in the case of homosexuality, atypical, (try that one for PC speak of things that veer from the mean, ballen) were genetic in nature.
Yes, most homosexuals are born that way-time will prove this out.
