Margaret Sanger, the founder of Planned Parenthood, has been the subject of adoring television dramas and enthusiastic biographies, but her life and work were anything but inspiring. Killer Angel is a close-up look at Sanger that brings to light much that has been ignored or suppressed in most of the films and books that are available today. Sanger's personal life was marked by tumult and immorality. The views underlying her formation of the American Birth Control League (renamed Planned Parenthood after World War II) were racist and White Supremacist.
