They have evidence showing, and there is no point in life where you simply "choose" to be gay. On the 60 Minutes story they had video of the various subjects when they were just 5 or 6yrs old, judging by their mannerisms alone they could tell if they were going to grow up gay or straight and in 100% of the cases they showed, they were correct. They also have other documented studies that showed strong evidence of this aswell, among other things I don't remember. It is genetic, its about time the majority of people accept that, allow gay rights, and move on. It makes me ashamed of America to have me think that the majority of American's haven't learned from the Civil Rights Movement in the 60's.
Some people have really fiery tempers, too, and have them from a young age. You can tell just from watching them at 5 to 6 years old if they'll grow up to be aggressive. However, some of them learn to control their temper.
I'm just saying that it's not genetics or society alone, but the interplay between the two, that determines a lot of personality traits. If we were truly slaves to genetics, it would be foolish to imprison criminals, since they couldn't help their behavior.

Homosexuality is observed in some animals.
My thoughts on it - it's a birth defect. A normal animal or human is normally attracted to the opposite sex, just as a normal human is supposed to have two arms and two legs. Something just goes awry in the development process in the womb, and the fetus' brain isn't programmed according to the sex of the body.
Left to the forces of nature, birth defects generally don't get passed on - homosexual animals would be attracted to their own sex, and thus would not pass on their genes. Natural selection at work.
Except that if you consider the selection pressure against true homosexuality, it would have been gone a long time ago if it was 100% genetic. We carry a number of benign "defects", and a few not-so-benign, but there will be a low incidence of defects that SERIOUSLY inhibit reproductive success in a healthy population.
If there was a genetic mutation that would make .5-5% of the population (depending on whose figures you believe) get testicular cancer prior to the reproductive years, do you think it would last very many generations?
How long do you think the sickle cell gene would last? There may be tremendous reproductive advantages to a female chimp to have a gay brother and or sister, as well as advantages to the whole tribe. Evolution is not about individuals but genes.
