Does Religion Always Cause Political Intolerance?

Should fringe groups, even offensive groups like the Ku Klux Klan, be allowed to have a voice in American politics? Since the 1950s, social scientists have recognized that very religious people are more likely to answer "no" to this type of question. In other words, religion and political intolerance often go hand-in-hand. But why is this the case? Political scientist James Gibson discusses the intersections between faith and intolerance and explains why, though these ideas can often connect, having faith does not make a person less tolerant.
