Well, it seems that, after examining 49 years of evidence, that a panel of the American Psychological Association says that therapy to "change" from gay to straight doesn't work. (Boy howdy, now there's a surprise, eh?)
This article says that the panel voted 125-to-4 that this kind of change is unlikely and attempts to enforce this kind of change lead to depression and suicidal tendencies. As an alternative, for patients who are having problems reconciling their sexual orientation and their religious faith, therapists are being urged to consider such things as recommending switching churches.
This has been a long time in coming, but it's really nice that the religion is finally being regarded as the choice and the sexual orientation as the immovable object.
