Outing
Outing is the act of disclosing an LGBTQ person's sexual orientation or gender identity without their consent. It is often done for malicious reasons, either to instrumentalize homophobia, biphobia, and/or transphobia in order to discredit someone, or to combat homophobia, heterosexism, and/or cissexism by revealing that a prominent or respected individual is homosexual and/or transgender.
