Ryan Murphy has long made diversity an important part of his TV shows.

The television creator sat down with activist and author Janet Mock at the Time 100 Summit in New York City this week and talked about bringing underrepresented voices to the small screen.

“If you’re not writing about women or gender or race, you’re not writing,” Murphy said. “Those are the stories that people want to talk about.”

Among the shows with diverse casts and production teams that Murphy has created are “Glee”, “American Horror Story” and “Pose”, on which he has collaborated with Mock.

Mock, who is transgender, praised Murphy for bringing marginalized people into the creative process to tell their stories.

“No longer is it okay for someone so dominant to tell the stories of the marginalized,” she said. “You need to bring them on as collaborators.”
