The essay discusses the negative effects of the politicization of religion in the U.S. The authors note that modern U.S. partisan politics are characterized by conflict between religious conservatives and secular progressives. They explain the development of American religiosity since the 1950s, giving particular focus to the rise of evangelicalism. It is concluded that the religious character of U.S. conservatism has led moderates and liberals to feel disdain for religion in general.
