There's a new CBSN documentary, The Right’s Fight to Make America a Christian Nation: “The debate over what role religion should play in public life has never been more contentious, with some promoting a vision of Christian primacy that critics say tramples on the rights of everyone else.”
teachings of the Bible are so muddled and self-contradictory that it was possible for Christians to happily burn heretics alive for five long centuries. It was even possible for the most venerated patriarchs of the Church, like St. Augustine and St. Thomas Aquinas, to conclude that heretics should be tortured (Augustine) or killed outright (Aquinas). Martin Luther and John Calvin advocated the wholesale murder of heretics, apostates, Jews, and witches. - Sam Harris, "Letter To A Christian Nation"
