Homosex
As a gay man I'd like you to stop grouping me in the same category as someone with a mental illness. The reason why the APA stopped classifying it as a MD is not based on scientific evidence but rather on social stigma. And while American physiologists did think homosexuality was a MD up til the 70s, same sex attractiveness is a completely separate from thinking you are in the wrong body. A Gender dysphoric brain chemistry is closer to schizophrenia chemistry than homosexuality.
This right here.
