In an extended conversation about a recent Pew survey of the American religious landscape, Nancy Ammerman, a professor of the sociology of religion at Boston University, explains what it it means to choose your religion and the importance of choice in the Protestant tradition. She also discusses the influence of Protestantism on other religions in American culture, the arrival of new Christian immigrants to America, and the important influence of gender and complicated family issues such as intermarriage, birth control, divorce, and separation on the choices Protestants, Catholics, and others are making about their religious affiliations.
