When did the genome project determine that nobody is born that way? I am sure it is BOTH and more than likely for those that it is a choice they are the most vocal.
To me, the cause of the predisposition does not matter. Acting on those desires violates just about any norm you can think of. We all have desires, however, being intelligent humans we do not act on the ones that society frowns upon.
I, for one, would like to exterminate a certain group of excrement claiming to have a religion that is offended by everything. I have not acted on that burning desire. Why can't the butt pirates keep it in their pants?
Because rump rangers are not responsible for their own behavior and we need to give them entitlements.
Its far more choice than biology... its not mere biology that gay men tend in large numbers to fall into 1 of three categories:
1) Horrible or no relationship with a father growing up.
or
2) Overbearing mothers
or
3) Molested by men as children.
None of those factors has anything to do with biology, yet they are all very very common themes among homosexual males.

The Genome Project didn't involve the search for genetic causes of diseasese, disorders and/or behaviors. It mapped existing genes throughout our human population. Your implausible reply there (that "the genome project" didn't "determine that nobody (was) born that way" or did) would be like telling someone that Google Maps didn't write prescriptions so therefore no prescription for anything existed.
There has been no genetic proof or substantiation that homosexuality is "immutable." That means, no one has been able to ever isolate any genetic cause.
Despite the pleas and insistences of some that homosexuality is an immutable characteristic (that people "are born homosexual"), it is not proven to be the case and remains just that: a personal opinion and in the case of many, an obsession. Neither of those things establishes scientific proof.
So, homosexuality remains a behavior. It's not immutable.
It hasn't yet. But every other study has shown that there is no genetic link. Of course the fact that the overwhelming majority of sodomites share one of three environmental characteristics also helps. (Poor or absent relationship with their father, being sexually or otherwise abused, being relentlessly teased by their peer group during the formative years)
