In 1973, America's mental health authorities switched gears, declassifying homosexuality. The story of how that decision came about will make your jaw drop.
The statement "science says homosexuality is not disordered" is so blatantly nonsensical as to be comical. What is considered "disordered" is wholly outside of science, instead it is dictated by our values and goals. A broken limb or psychopathy are only disordered if you consider those states contrary to the values of: being capable of performing physical tasks, not burdening other people, material well-being of society, etc etc.
