Geesh, I hope they got paid to write this. I just love how they describe mainstream psychological practice as "traditional." There is no proof that reparative therapy works. Furthermore, it is harmful to individuals and to the GLBT community as a whole because it bolsters a weak argument that people can and should change their sexuality.
The problem is not someone's sexuality. The problem is legal discrimination and social intolerance that conspire to keep people in the closet or pressure them to be something they aren't.
I know people who tried to "pray the gay away" and endure years of bizarre "therapies." They wanted it to work. They tried to be straight. It failed. These efforts to change sometimes lead to suicide because as time goes on and nothing works, people become hopeless.
