"The research on homosexuality is very clear. Homosexuality is neither mental illness nor moral depravity. It is simply the way a minority of our population expresses human love and sexuality. Study after study documents the mental health of gay men and lesbians. Studies of judgment, stability, reliability, and social and vocational adaptiveness all show that gay men and lesbians function every bit as well as heterosexuals. "

"Nor is homosexuality a matter of individual choice. Research suggests that the homosexual orientation is in place very early in the life cycle, possibly even before birth. It is found in about ten percent of the population, a figure which is surprisingly constant across cultures, irrespective of the different moral values and standards of a particular culture. Contrary to what some imply, the incidence of homosexuality in a population does not appear to change with new moral codes or social mores. Research findings suggest that efforts to repair homosexuals are nothing more than social prejudice garbed in psychological accouterments"

In 1973, the American Psychiatric Association removed homosexuality from its Diagnostic and Statistical Manual of Psychiatric Disorders.
