To Cure a Sinful Nation: Conversion Therapy in the United States is the first book-length work to explore the epic story of conversion therapy from the late nineteenth century to today. By braiding intellectual, medical, social, and political history, this book examines how efforts to change sexual orientation have been a defining feature of modern American life. To Cure a Sinful Nation is sweeping in scope, highlighting the rise of conversion therapy over the first half of the twentieth century. The second half of the book then examines how the debate over conversion therapy has shaped our contemporary world. To Cure a Sinful Nation underscores how the fight over conversion therapy has been about more than specific therapeutic and counseling practices, though. The concurrent rise of the gay rights movement and family values conservatism has had far-reaching implications for the country. The battle over conversion therapy has not only been central to political contests between gay activists and religious conservatives but has been at the heart of the American democratic experiment in the post-World War II era. It is thus impossible to understand where we are today without a comprehensive examination of conversion therapy’s 140-year history in the United States.
