Why does the government care about labeling your gender?

A person’s sex designation on official documents has a lot to do with the state they live in. Paisley Currah is professor of political science and women’s & gender studies at Brooklyn College and the Graduate Center of the City University of New York. He joins host Krys Boyd to discuss the category of “sex” on government documents and what that says about the future of transgender rights. His book is “Sex Is as Sex Does: Governing Transgender Identity.”
