I don't have my normal links handy. Find Scripter (I think he's on this thread up a ways), click his name, and read the links he's got about former homosexuals. Read their stories, and read what those who have treated thousands of homosexuals have found.
There aren't 4000 causes of homosexuality. It's becoming more and more clear what the causes are, and those who want out of the "gay" life have a good chance, if they hear the truth. If the lie is told that "you were born that way and can't change", then they don't seek the help that is available.
If you want to discuss this issue with me please read my comments more carefully. I said no such thing.
