And not one of my gay friends would agree with you. Every one of them laughed at the idea that being gay was genetic. ("Yeah. I got the gay gene from the man who had sex with my mother... riiiight.") They all told me that they had terrible, traumatic childhoods. Some of them were just deeply neglected or felt outcast and were looking for a place to belong. Being gay is a combination of sex and a twisted mental development.
Better than being a serial killer or into a fire thing...
In the prior discussion I did not even say anything about whether being gay was genetic,. My point was that people can choose their sexual behavior but not their sexual feelings.
But now that you mention it, I do not think that a poll of your particular gay friends is a good way to determine the truth concerning the origin of sexual preference. Apparently many gay people did not have traumatic childhoods and many do believe that being gay has a genetic component as they have relatives who are gay or bisexual. Even if being gay is not genetic, it is still possible that exposure to incorrect levels of hormones during gestation influences eventual sexual preference before birth. For instance, 37 percent of female infants born with a condition called congenital adrenal hyperplasia (CAH) eventually become lesbian. link
