In God’s Angry Men, Carmen Celestini brilliantly traces the enduring shadow of the John Birch Society across American political and religious life. Combing archival research with years of experience studying extremist movements, she shows how a mid-century movement once dismissed as fringe became the blueprint for the Christian Right’s fusion of apocalyptic faith, libertarian economics, and conspiratorial politics. This is not only a study of the past, but a chilling genealogy of the present—revealing how the rhetoric of free enterprise, divine destiny, and moral panic continues to animate today’s populist and evangelical movements.
