Any country that enjoys fighting and bitching as a recreation as much as America does will always be, in some way or another, walking along a knife's edge. We're a nation that spends its afternoons watching white trash throw chairs at each other on Jerry Springer, its drive time listening to the partisan rantings of this or that hysterical political demagogue, and its late-night hours composing feverish blog entries full of anonymous screeds and denunciations. All of this shit is harmless enough so long as the power comes on every morning, fresh milk makes it to the shelves, there's a dial tone and your front yard isn't underwater. But it becomes a problem when the magic grid goes down and suddenly there's no more machinery between you and whomever you happen to get off on hating.
