Why do you spell it that way? We don't know jack about what all our DNA codes for, although we're working on it. Sorry to disappoint you, but nearly all adults who self-identify as gay report that they had that orientation even as a young child. These are ppl who come from diverse family backgrounds so we can't blame "poor parenting," "domineering mother and weak father," "gang rape by males," etc. Homosexuality is also found in the animal kingdom as well. It's an aberration (used in the scientific sense) that affects a very small percentage of a given species' population. Sorry you have issues with your fellow citizens who are gay. As a straight person, I do not... just like most straight ppl do not. Why does this bother you?
to be fair, anecdotal accounts are not evidence of a gay gene.
A lot of indians like indian food. I hate indian food. If I ate indian food my whole life, maybe i'd like it. Yet even without a genetic reason, different sets of people are different depending on their environment.
Now I am not saying there isn't something linking people being gay genetically either, I am simply saying we don't really know yet. It could be an environmental thing.
