The National Association for Research & Therapy of Homosexuality (NARTH) takes takes issue with how the mental health society describes the success of conversion therapy. NARTH also takes issue with how the mental health society describes sexual orientation for two reasons. One reason is because it is not a fixed two part quality. The second reason is because it is not a disease. Instead, it describes as a continuous order of sexual attraction and emotional attraction.

The positions also make an environment in which bias increases.
