Is anyone surprised?
It takes a special type of self hatred to continue to push conversion 'therapy' when the facts on it are clear as a bell - it does not work. It would not surprise me if the majority of people involved in such endeavors turn out to be gay or some other sexual orientation outside normal.
I honestly have no idea how conversion therapy works, I would imagine it would be similar to whatever type of therapy is use for people like Weiner. I'm not saying there is anything wrong with people being gay, but just question if people (adults) should have a choice in the type of therapy the feel may be best help them.
Gays say they are born this way and that it's not a choice, but transgenders say they are born in the wrong body, or whatever, and for them it is a choice. So why is it not also a choice for someone who is born gay but feels heterosexual?
