On this week’s episode of The Waves, Slate homepage editor Sol Werthan sits down with trans rights activist and author, Paisley Currah. They discuss Paisley’s new book, Sex Is As Sex Does and discuss why “male” and “female” are used as a legal and social classifier. And why, even for cis people who identify with the gender binary, that might not be the right way to go.

In Slate Plus, Sol and Paisley talk about the politicization of trans kids.

Podcast production by Cheyna Roth with editorial oversight by Shannon Palus, Daisy Rosario and Alicia Montgomery.
