California is seen as one of the most liberal states in the U.S. in regard to lesbian, gay, bisexual, transgender (LGBT) rights, which have received nationwide recognition since the 1970s. Same-sex sexual activity has been legal in the state since 1976. Discrimination protections regarding sexual orientation and gender identity or expression were adopted statewide in 2003. Transgender people are also permitted to change their legal gender on official documents without any medical interventions, and mental health providers are prohibited from engaging in conversion therapy on minors.
