Sexual orientation discrimination refers to the unfair treatment of individuals based on their sexual orientation, whether they identify as gay, lesbian, bisexual, or heterosexual. This type of discrimination can manifest in various areas of life, including employment, housing, and public accommodations, and it often stems from societal stigma and prejudice against LGBTQ+ individuals. The fight against sexual orientation discrimination has been a central issue within the gay rights movement, particularly highlighted by events such as the Stonewall Riots, which catalyzed activism for LGBTQ+ rights and equality.
