Some psychologists and activists believe that the diagnosis of gender dysphoria should be removed from the DSM because being transgender is a social identity rather than a mental illness, that the label may contribute to stigma towards trans people, and that the diagnosis echoes the previous classification of homosexuality as a mental disorder.
The World Health Organization, for example, maintains a diagnostic manual called the International Classification of Diseases. In 2018, the organization removed the mental disorder “gender identity disorder” and included “gender incongruence” in the sexual health section instead.
