Mass shootings, domestic terrorist attacks, acts of extremism. These are stark realities of everyday life in the 21st century, but they’re also almost always carried out by men or boys fueled by hatred of one or more targeted groups of people. Man Up: The New Misogyny and the Rise of Violent Extremism, the revelatory new book by American University scholar and sociologist Cynthia Miller-Idriss, addresses these uncomfortable truths head-on, confronting the motivations behind such acts in an effort to understand and prevent the rising tide of violence. Miller-Idriss talks about these and other hot-button issues with Vermont journalist Garrett M. Graff at Phoenix Books in Burlington.
