I'm not informed about what you are talking about, but you are wrong about the ability to change.
Why should someone who has been molested be denied the opportunity to change their conditioned attraction.
Why should they be punished a second time by being told they must accept the "orientation" foisted upon them?
In the only serious attempt to measure change, the largest degree of change seen was change from being a bisexual with a modest same-sex preference to being a bisexual with a modest opposite preference. You can train people not to act on their orientation, but you can't train theri orientation out of them.
It's curious how being molested by a man supposedly makes men like having sex with men and women hate having sex with men. The reality is that molestation does not alter orientation.
