Nate Cohn: “Whether religious or political, sectarianism is about two hostile identity groups who not only clash over policy and ideology, but see the other side as alien and immoral. It’s the antagonistic feelings between the groups, more than differences over ideas, that drives sectarian conflict.”
“Any casual observer of American politics would agree that there’s plenty of hostility between Democrats and Republicans. Many don’t just disagree, they dislike each other. They hold discriminatory attitudes in job hiring as they do on the Implicit Association Test. They tell pollsters they wouldn’t want their child to marry an opposing partisan. In a paper published in Science in October by 16 prominent political scientists, the authors argue that by some measures the hatred between the two parties ‘exceeds longstanding antipathies around race and religion.'”
