And . . . therefore, what? A lot of people were physically abused by beatings as minors. So what? A lot of people had drunk parents. So what?
Homosexuality is a "Character and Behavior Disorder" no matter what the psychological world says, similar to being an alcoholic, thief, gambler, etc., all of which deserve therapy, either religious, secular, or both. But to pat them on the back is insane.
And therefore their hommosexuality is a behavioral response to the abuse, and NOTHING to do with genetic factors.
I think an “all-of-the-above” model for understanding the genesis of homosexual behavior has better explanatory power than just focusing on only one area, such as abuse.
“Generally, the histories of men engaging in same-sex behaviors reveal a history of cumulative problems: significant peer rejection, low self-esteem, a distant father, an overprotective or controlling mother, victimization by bullies, or sexual abuse. Fortunately these conflicts can be resolved, and the masculine identity can be strengthened and then embraced. “

In general, NARTH (http://narth.com/) is a pretty good resource for info on GID (Gender. Identity Disorder). And I don’t think it’s problematic to recognize it as a disorder. Being a disorder does not put it outside the moral, decisional realm. Quite the opposite. For a wide range of disorders, therapeutic solutions that work well consistently require the patient to make life-changing choices about their behavior. But recognizing potential root causes empowers the therapist and the patient to locate and lock onto those decisional behaviors most likely to bring about real healing, and that’s all good.
