Sexuality and gender identity–based cultures
Sexuality and gender identity-based cultures are subcultures and communities composed of people who have shared experiences, backgrounds, or interests due to common sexual or gender identities. Among the first to argue that members of sexual minorities can also constitute cultural minorities were Adolf Brand, Magnus Hirschfeld, and Leontine Sagan in Germany.
