Book excerpt: The first book to explore menstruation in the current cultural and political landscape and to investigate the new wave of period activism taking the world by storm. After centuries of being shrouded in taboo and superstition, periods have gone mainstream. Seemingly overnight, a new, high-profile movement has emerged—one dedicated to bold activism, creative product innovation, and smart policy advocacy—to address the centrality of menstruation in relation to core issues of gender equality and equity. In Periods Gone Public, Jennifer Weiss-Wolf—the woman Bustle dubbed one of the nation's “badass menstrual activists”— explores why periods have become a prominent political cause. From eliminating the tampon tax, to enacting new laws ensuring access to affordable, safe products, menstruation is no longer something to whisper about. Weiss-Wolf shares her firsthand account in the fight for “period equity” and introduces readers to the leaders, pioneers, and everyday people who are making change happen. From societal attitudes of periods throughout history—in the United States and around the world—to grassroots activism and product innovation, Weiss-Wolf challenges readers to face stigma head-on and elevate an agenda that recognizes both the power—and the absolute normalcy—of menstruation.
