Even the most strait-laced small town probably rolled its collective eyes at those delicate souls who supposedly used chintz ruffles to hide piano legs from the imagined stares of lascivious men. We moderns haven’t yet developed any such filters. Today’s vaporing maiden aunts fell for an adolescent prank that gulled them into believing that the thumb-and-forefinger “okay” sign was a secret white-supremacist symbol . . . and rather than ever admit they were fooled, or that it’s a bad idea to voluntarily cede harmless gestures to racist lunatics, things escalated until the U.S. Naval Academy and West Point were investigating whether midshipmen and cadets were making an “okay” sign at this year’s Army-Navy football game.

It would be too neat a bit of plotting if the decade ended with the discovery of the antidote to this proscription plague. Yet I wonder if that isn’t what happened when the mob decided to cancel J.K. Rowling, and she demurred.

Rowling’s tweet earned her all the denunciations and anguished think pieces that a good mobbing entails. The usual script for what would follow: Rowling vanishes the tweet, apologizes and goes on a listening tour until she had been sufficiently reeducated to explain how wrong she’d been. But Rowling didn’t recite her lines.
