I'm of the opposite position. A disorder is a medical diagnosis that is treated by medical professionals. Making diagnosises into social categories is what I'm absolutely against because it conflates what a diagnosis is. I don't want to see the normal spectrum of human functioning and coping to be medicalized. I want people to feel secure in finding their best way to function outside of a medical context if appropriate. That was frankly the problem with having homosexuality as a disorder in the DSM. It was pathologized inappropriately.
