The political left in the United States, and more particularly the Democratic Party, seems to be in a process of self-immolation. Analogously to historical Protestantism, it is not defined by any coherent, substantive policy or body of doctrine. Instead, it is constituted by assertions of what it is not. And the left is increasingly defined by resentment, fury, and irrational hatred of all things that are not left-wing. Thus, when the left urgently needs to articulate coherent policy in order to answer its opponents, it has no intelligible theory. Rather, it is reduced to screaming at its opponents, stomping its feet, and calling everybody Nazis. Disagreement is genocide.
