California is seen as one of the most liberal states in the U.S. in regard to lesbian, gay, bisexual, transgender (lgbtq+) 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.
California se convirtió en el primer estado de EE. UU. en legalizar las uniones domésticas entre parejas del mismo sexo en 1999. El matrimonio entre personas del mismo sexo se legalizó en 2008 durante cinco meses hasta que los votantes aprobaron una prohibición en noviembre del mismo año. Después de que la Corte Suprema de EE. UU. se negara a reconocer la posición legal de los opositores al matrimonio entre personas del mismo sexo el 26 de junio de 2013, la prohibición ya no era aplicable, lo que permitió que los matrimonios entre personas del mismo sexo se reanudaran a partir del 28 de junio. La adopción entre personas del mismo sexo también ha sido legal en todo el estado desde 2003, permitiendo la adopción de hijastros y la adopción conjunta entre parejas del mismo sexo.
In 2014, California became the first state in the U.S. to officially ban the use of gay panic and transgender panic defenses in murder trials. Public schools are also required to teach about the history of the lgbtq+ community and transgender students are allowed to choose the appropriate restroom or sports team that match their gender identity. Most support for lgbtq+ rights can be seen in the largest cities, such as Los Angeles, San Diego, and San Francisco, as well as many cities on the Pacific coast. A 2017 survey from the Public Religion Research Institute showed that 66% of Californians supported same-sex marriage.
