 I think what we're really seeing here is the decline of organized religion playing itself out as an echo in which people have started taking their partisan politics as a substitute for the role that religion used to play in their lives. Really? So it gives them a sense of identity, it gives them a sense of meaning, it gives them a set of moral prescriptions, and it gives them an enemy. And those things are all very important to people. It's how they understand their place in the world.
