Catholics Against Militarism (CAM) is an informal, grassroots, Internet-based movement of lay Catholics that seeks to identify and respectfully challenge militaristic attitudes in the U.S. Catholic Church. We conduct interviews with Catholics and other Catholic groups who are: 1) successfully registering dissent at the parish level, 2) raising awareness of the dangers of militarism through dialogue with fellow believers, and 3) spurring deeper, more honest reflection on the role of violence in our world.
