From an APA meta analysis of 87 studies conducted between 1960 and 2007:
...there is little evidence that efforts to change a person's sexual orientation from gay or lesbian to heterosexual are effective...[and] such efforts may cause harm.
The study goes on to say they either supress their urges or just plain fake it. You don't say. For more in that category, consider that those is such programs often experienced "loss of sexual feeling, suicidality, depression and anxiety...emotional and spiritual distress and negative self-image"
Yes, all the sorts of experiences you'd expect from someone being told that what they are, not merely what they do, is immoral and evil and must be changed. This flies in the face of the claims by those pious pricks who run these programs that sexual orientation is a mere choice. But then anyone who has known gay people for who they are knew that already.
The task force noted that some people attempt to change their sexual orientation because it conflicts with their religious beliefs, and recommended that their mental health care providers help them "explore possible life paths that address the reality of their sexual orientation, reduce the stigma associated with homosexuality, respect the client's religious beliefs, and consider possibilities for a religiously and spiritually meaningful and rewarding life."
"In other words," said Glassgold, "we recommend that psychologists be completely honest about the likelihood of sexual orientation change, and that they help clients explore their assumptions and goals with respect to both religion and sexuality."
In other words, your agenda is contradictory and doomed to failure because you are suggesting feeding the very beast that caused the problem in the first place: religion. Respecting their religious beliefs means ignoring the reality of their orientation! This is one of those places where science and religion are saying completely contradictory things:
Though all mainstream health and mental health organizations concluded years ago that homosexuality is not a mental disorder, the American Psychological Association formed the task force to work on the report two years ago after noting a resurgence of groups that identified homosexuality as a defect or spiritual or moral failing.
Yes, and you people with the science on your side need to make it crystal fucking clear that the evidence implies that homosexuality is not a spiritual or moral failing in any way that can be measured, and that people making such proclamations are simply wrong. They do not have "another way of understanding the world". They have a bunch of bronze-age made-up crap, and there is no reason people living in the modern world with a modern understanding of it should give any credence to those bringing a knife to a machine gun fight. It does real damage in real people's lives. Keep your comfy baseless thoughts inside your heads where they belong and out of everyone else's lives.
