Seems to me that in many cases homosexuality is one symptom (amongst many) of severe emotional trauma. It is a coping mechanism. Ergo, for society to normalize homosexuality and declare it to be healthy, wholesome, normal, and natural does the homosexual no favors.
This is perhaps the saddest aspect of the entire homosexual conflict. Homosexuals delude themselves that they are happy when they are not, and society reinforces their delusion. In the mean time, the underlying trauma is ignored for the sake of normalizing homosexuality.
By the way, the APS denies that homosexuals are more likely than others to experience other psychological disorders.
Nobody is doing homosexuals any favors by telling them they are okay and normal.
Your post totally nailed it. (No pun intended.)
Talk show host Roy Masters has a great article on the causes of homosexuality: http://www.fhu.com/articles/gays_in_society.html
