For decades, the story of the American feminist movement seemed like a progression of hard-won gains: Title IX, Roe v. Wade, the Violence Against Women Act, #MeToo. But in a post-“lean in” and post-Roe America, the momentum seems to have reversed, leaving some feminists to wonder: What are we fighting for? And who is in that fight? So this week, “The Argument” is kicking off a three-part series to dive into the state of feminism today. In the first episode, Jane Coaston brings together two people who have helped shaped how we think about feminism. Anne-Marie Slaughter is the chief executive of New America and wrote the influential 2012 Atlantic essay “Why Women Can’t Have It All.” The article was critiqued by our second guest, Tressie McMillan Cottom, a sociologist at the University of North Carolina, Chapel Hill (and a Times columnist). Ten years later, the two women discuss what’s next for feminism — personal disagreements included — and debate Jane’s fundamental question: Is feminism an identity that you claim or an action that you take? (A full transcript of the episode will be available midday on the Times website.)
