The ex-gays advocates aren’t being honest (an understatement, I know) and there’s no evidence to back up their claims:
There is no evidence to support the claims of some practitioners that sexual orientation can be changed through therapy, a special committee of the American Psychological Assn. reported today. Mental health professionals should not tell patients that they can change their sexual orientation and instead should help them “explore possible life paths that address the reality of their sexual orientation,” according to the report, which was released at a Toronto meeting of the association and online.
From the American Psychological Association release:
The American Psychological Association adopted a resolution Wednesday stating that mental health professionals should avoid telling clients that they can change their sexual orientation through therapy or other treatments.
The “Resolution on Appropriate Affirmative Responses to Sexual Orientation Distress and Change Efforts” also advises that parents, guardians, young people and their families avoid sexual orientation treatments that portray homosexuality as a mental illness or developmental disorder and instead seek psychotherapy, social support and educational services “that provide accurate information on sexual orientation and sexuality, increase family and school support and reduce rejection of sexual minority youth.”
The approval, by APA’s governing Council of Representatives, came at APA’s annual convention, during which a task force presented a report that in part examined the efficacy of so-called “reparative therapy,” or sexual orientation change efforts (SOCE).
This won’t stop the ex-gays, but it shows they practice junk therapy.
