Fight for transgender equality transcends generations

Nicole Maines – a transgender actress who has starred in “Supergirl,” “Yellowjackets,” and more – never intended to become an activist.

But when she and her family won a groundbreaking case against her school district in 2014, arguing that the school could not deny her access to the girl’s bathroom because she was transgender, the role came naturally.

Years later, Maines would go on to make history again as the first live action transgender superhero on television as Dreamer in “Supergirl."

Maines spoke with ABC News in 2015, sharing the excitement she felt about preparing to undergo gender affirming surgery.

“I just knew in my head and in my heart that I was supposed to be a girl,” she said in the 2015 interview. “It was just the voice in my head telling me, ‘No, this is who you are, you need to be a girl.’”
