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.
