DUDE, do you actually read what you post/link?
when asked if sexual orientation can be changed by therapy, the APA adamently stated NO! Then they followed up with a paragraph that says they "dont have enough proof if the therapy some have received and claim to have changed them, actually works or not"
How the hell can they make a claim when the evidence is non conclusive, or, at best, shows there can be a change.????
"Some therapists who undertake so-called conversion therapy report that they have been able to change their clients' sexual orientation from homosexual to heterosexual. Close scrutiny of these reports however show several factors that cast doubt on their claims. For example, many of the claims come from organizations with an ideological perspective which condemns homosexuality. Furthermore, their claims are poorly documented. For example, treatment outcome is not followed and reported overtime as would be the standard to test the validity of any mental health intervention"
As for the "choice" issue:
"Although we can choose whether to act on our feelings"
so, apparently they at least think there is partly a choice in the matter, and have no proof one way or the other (although they have to claim the changed patients are not telling the truth) if it can be changed.
