You would expect, in a time of uncertainty, a landscape crowded with frauds and con artists peddling positive formulas for happiness, love, sex, good health, and better government. You would expect, too, the most trivial assertions to be attended with much noise and thunder: absent authority, every message must be shouted to have a hope of being heard. Stridency will infect every mode of communication, but will be most disruptive of political rhetoric. Just to keep an audience, politicians and commentators will have to scream louder and take more aggressive positions than the competition.
