Jan 10, 2026
David Renton, a historian and author, and Elane Heffernan, a former SWP member and activist, dive deep into the fallout of the Socialist Workers Party's infamous scandal. They explore the party's historical allure and the toxic culture that led to its decline, particularly its treatment of sexual assault complaints. Elane shares her personal journey of disillusionment, while David highlights structural issues and the failure to confront feminism’s role. Together, they discuss practical reforms for political organizations to prevent such failures in the future.
