Kevin D. Williamson—the lively, literary firebrand from National Review who was too hot for the Atlantic Monthly—comes to bury democracy, not to praise it, in his irrepressibly readable new book sure to outrage and illuminate, The Smallest Minority: Independent Thinking in the Age of Mob Politics. Funny, profane, and profound, Williamson takes a flamethrower to social-media mobs, literal mobs, and the enforced conformity of identity politics in this thinking man's political book of the year.
