"GSA clubs–originally called Gay-Straight Alliance clubs when they first established in the 1980s–are student-run organizations, typically in a high school or middle school, which provide a safe place for students to meet, support each other, and talk about issues related to sexual orientation and gender identity and expression. There are three typical functions of a GSA club: Support, Social, and Activist.
While GSA clubs have traditionally served as safe spaces for LGBTQ+ youth to build awareness and community as well as prevent discrimination and harassment in schools, they are now emerging as vehicles for deeper social change that extends beyond individual schools. Trans and queer youth are building their power through GSA organizing and connecting to state and national campaigns on a variety of issues that affect all students across the country." - https://gsanetwork.org
