Simon Doonan had a childhood rife with delightful moments of sarcasm. A teacher once told him, after a particularly bad reading of a page from Ulysses, that Doonan's "sensitive" delivery had left him overwhelmed with emotion (and in need of a cigarette). His parents, when Doonan started dressing like a glam rocker, often informed him of the location of the nearest traveling circus. None of that scarred him for life—rather, it made him a better person—which is why our all-too-sincere society needs to loosen up and embrace sarcasm once again, Doonan writes in Slate.
Nowadays, make a sarcastic comment to a friend and you're likely to find yourself branded a "hater." But "sardonic irony is as critical to healthy child development as vitamins and tick-checks," Doonan writes. "Raising your brats on an exclusive diet of sincerity is a recipe for disaster. The current mania for relentless positivity and self-esteem building leaves me convinced that we are in real danger of turning out an entire generation of inspirational speakers."
