I am having a debate with a buddy on this and since my very controversial thread "my opinion on gays" I realized I knew shit.
So I went out and researched. This is still a very, very controversial topic (nature vs. nurture) and I finally came to the realization that it's possible it could be a little of both.
So tell me what you think of this:
Homosexuality is derived from not only the environment one is brought up in, but also as a result of genetic predisposition to their sexual preference.
I read an article about how chemical changes in the womb after pregnancy can allow for the second child to have a greater inclination to become gay or lesbian. Even though I still believe that it's human nature to be heterosexual (as the majority of all mankind has been) there most likely is a gene that allows for that allows for it to be brought out.
Maybe I'm straight up wrong, who knows. I heard some pretty good answers in the last thread let's hear some now.
