What is a gay straight alliance club

Genders & Sexualities Alliances, or GSAs for short, are student-run organizations that unite LGBTQ+ and allied youth to build community and organize around issues impacting them in their schools and communities.
A gay–straight alliance, gender–sexuality alliance (GSA) or queer–straight alliance (QSA) is a student-led or community-based organization, found in middle schools, high schools, colleges, and universities. These are primarily in the United States and Canada.
