THREAD. Emma Gonzales is president of the Gay-Straight Alliance. 
I was president of my GSA too, then organized LGBTQ youth on the early internet, then studied adolescent psych at Harvard. I've got something to say about high-school GSAs in America. 1/
A GSA serve three purposes: support, education, and activism.
SUPPORT means it is a safe place to be yourself if you are LGBTQ. You can meet other LGBTQ kids and allies there, as well as safe adults. You can make friends who will love you for who you are. 2/
