Some background information: I had a really close friend of mine ask me if gays were born that way or if it's a choice. From the knowledge that I learned from the teachers at my school, I answered him saying that gays are just born that way, and they do not find out until they're teenagers. Unfortunately, I was afraid that I may be misleading him so I told him I'll do some research to make sure that I am giving him right information, because my knowledge was pretty much from one health teacher from the ninth grade. Doing a quick good search led to a lot of biased information, so before I waste my time with a proper scholar search, I figured I'd ask PhysicsForums for their unbiased responses to the following questions: Are gay people born the way they are? Or is it something they learn? If you answer to "yes, gay people are born that way" to the previous question, is it still possible to be gay without being born that way? If they are born that way, it it something they inherit? If it's something they inherit, is there a particular gene? I would really appreciate unbiased responses to the above information. It would be appreciated if you could enforce your arguments with credible studies. Please do not bring religion views or opinions into this.
