JACK SHAFER: The awesome stupidity of the calls to tamp down political speech in the wake of the Giffords shooting.

Sheriff Dupnik’s political sermon came before any conclusive or even circumstantial proof had been offered that the shooter had been incited by anything except the gas music from Jupiter playing inside his head.

For as long as I’ve been alive, crosshairs and bull’s-eyes have been an accepted part of the graphical lexicon when it comes to political debates. Such “inflammatory” words as targeting, attacking, destroying, blasting, crushing, burying, knee-capping, and others have similarly guided political thought and action. Not once have the use of these images or words tempted me or anybody else I know to kill. I’ve listened to, read—and even written!—vicious attacks on government without reaching for my gun. I’ve even gotten angry, for goodness’ sake, without coming close to assassinating a politician or a judge.

From what I can tell, I’m not an outlier. Only the tiniest handful of people—most of whom are already behind bars, in psychiatric institutions, or on psycho-meds—can be driven to kill by political whispers or shouts. Asking us to forever hold our tongues lest we awake their deeper demons infantilizes and neuters us and makes politicians no safer.

The call by Sheriff Dupnik and others to take our political conversation down a few notches might make sense if anybody had been calling for the assassination in the first place, which they hadn’t.

Hey, even the term “campaign” has military roots.
