Studies continue, but they won't amount to much, I think. The "nuture" factors are simply too overwhelming. There is really no SCIENTIFIC way to study human behavior, especially when it's retroactive. SCIENTIFIC involves blind studies, random sampling, pre-post tests, LONG term studies involves millions and millions and millions of people. Given that, people forget, exaggerate, say what the "scientist" wants to hear, lie, learn what to say from therapists and plain just don't remember.
I think the puzzle will be solved with DNA and genetic studies. It WON'T solve the problem, but at least folks will know how and why things are the way they are.
I feel very sorry for homosexuals, bisexuals and transgenders. How very sad to be born or end up with SUCH a profoundly abnormal view of one's own sexuality.
Mind you, I feel that way in my heart and brain, but when I see the homosexual agenda shoved in our faces, forced down our throats and legislated by asshole activist educators, mayors and judges, I often feel little sympathy.
The most recent genetics-based identical twin study re-confims for about the fourth time now, what other identical twins studies have shown, that homosexuality is not "genetic".
Identical twins have identical genes. If homosexuality was "genetic", then if one twin was homosexual, the other would be too. But this is not the case, far from it in fact.
Homosexuality has been proven by this study and multiple others to not be "genetic."
