LOL- you seem to want to believe that the only possible options are 'choice' or 'genetics'- science does not support either of those options.
The best alternative I have seen is epigenetics- but I no more care why someone is homosexual than I care why someone is left handed.
Some people are homosexuals- some people are left handed. Why they are is immaterial.
The only possible options are genetics or choice. First off, race is genetic. No matter what anyone says, you can't choose to be a black man. Or a white man. You were born the race you are. You can go through your life acting like a black man, but you're not.
Like race, our sexual identity is determined by our DNA. You are born either a man or a woman with the exception of an occasional freak of nature, which creates a hermaphrodite.
But a man going through life thinking he's a woman, or vice versa, is deceiving themselves into thinking they are something they're not. Worse yet, a person who surgically alters their own body to become something they're not, is committing a grievous crime against nature.
Religion is not genetic. Religion is a lifestyle choice. Owning a gun is not genetic. Owning a gun is a lifestyle choice.
What did my post say about religion or owning a gun? The point is that race and sex are both genetic.
Whether gay people are born that way or not is irrelevant. Civil rights under the Constitution of the United States of America have no meaningful connection to genetics.
Well, not any more, they did. How about you prove that the folks who proposed and ratified the 14th Amendment did so with the expressed intent to overturn the marriage laws in every State of the union.
