For those untouched by death this Christmas, someone else’s bewildering, shattering turn of fate ought to occasion a little modesty and circumspection. Instead, even by its usual execrable standards, the public discourse post-Newtown has been stupid and contemptible. The Left now seizes on every atrocity as a cudgel to beat whatever happens to be the Right’s current hottest brand: Tucson, Ariz., was something to do with Sarah Palin’s use of metaphor and other common literary devices — or “toxic rhetoric,” as Paul Krugman put it; Aurora, Colo., was something to do with the Tea Party, according to Brian Ross of ABC News. Since the humiliations of November, the Right no longer has any hot brands, so this time round the biens pensants have fallen back on “gun culture.” Dimwit hacks bandy terms like “assault weapon,” “assault rifle,” “semiautomatic,” and “automatic weapon” in endlessly interchangeable but ever more terrifying accumulations of high-tech state-of-the-art killing power. As the comedian Andy Borowitz tweeted, “When the 2nd Amendment was written the most lethal gun available was the musket.” …

Nor am I persuaded by the Right’s emphasis on preemptive mental-health care. It’s true that, if your first reaction on hearing breaking news of this kind is to assume the perpetrator is a male dweeb in his early twenties with poor socialization skills, you’re unlikely to be wrong. But, in a society with ever fewer behavioral norms, who’s to say what’s odd? On 9/11, the agent at the check-in desk reckoned Mohamed Atta and his chums were a bit strange but banished the thought as shameful and discriminatory. In a politically correct world, vigilance is a fool’s errand. The US Airways cabin crew who got the “flying imams” bounced from a Minneapolis plane for flamboyantly, intimidatingly wacky behavior (praying loudly, fanning out to occupy all the exit rows, asking for seatbelt extenders they didn’t need) wound up in sensitivity-training hell. If a lesbian thinks dragging your wife around in a head-to-toe body bag is kinda weird, she’s being “Islamophobic.” If a Muslim thinks taking breast hormones and amputating your penis is a little off, he’s “transphobic.” These very terms make the point that, in our society, finding somebody else odd is itself a form of mental illness. In an unmoored age, what’s not odd? Once upon a time, TV viewers from distant states descending on a Connecticut town to attend multiple funerals of children they don’t know might have struck some of us as, at best, unseemly and, at worst, deeply creepy — a Feast of the Holy Innocents, so to speak.
