There are other studies which prove quite different results. Johns-Hopkins' latest belief -- after they closed their Homosexual Studies Program (whatever it was really called) -- is that homosexuality thrives in a cohort situation. If people in your community are ok with it, it is much more likely to thrive. It is a behavior that is CHOSEN. It is a habit/ behavior reinforced by doing it many times, hence harder to break the more you do it. As the fight intensifies, watch for more 'research' to support homosexuality. Lies can be used in any field to prove anything, if you have an agenda.
But again, I would like to reiterate my skepticism that homosexuality is chosen. The behavior is chosen but not the underlying desire. Homosexuality for most gay men appears to originate in childhood, before puberty; no one is making a conscious choice to be gay, it happens before such a choice is possible. Some claim that homosexuality is the result of weak fathers, sexual abuse by adults, rejection by peers, or childhood sexual experiences with peers -- but the problem with each of these claims is that there are a lot of children who experience these things who turn out heterosexual, and it is still very unclear what actually sends one child down one path and other child the other path. Genetics may play a role (based on the Bailey and Pillard twin studies), but that's unclear as well. The key thing to understand is most gay men report that they have no conscious memory of when or how they became gay. Also, most gay men report that their same-sex desires are as deeply determined as most heterosexuals report their opposite-sex desires to be deeply determined.
The only situation where homosexuality apears to be chosen is in prison or similar situations. However, in these circumstances, homosexuality is almost always a substitute for heterosexual behavior; men who have been in prison for many years and who have had only homosexual contact for that time, will immediately revert to heterosexual contact when it becomes available to them.
