Frank Rich’s column on shootings as predictable as you’d expect

Obama said, correctly, on Wednesday that “a simple lack of civility” didn’t cause the Tucson tragedy. It didn’t cause these other incidents either. What did inform the earlier violence — including the vandalism at Giffords’s office — was an antigovernment radicalism as rabid on the right now as it was on the left in the late 1960s. That Loughner was likely insane, with no coherent ideological agenda, does not mean that a climate of antigovernment hysteria has no effect on him or other crazed loners out there. Nor does Loughner’s insanity mitigate the surge in unhinged political zealots acting out over the last two years. That’s why so many — on both the finger-pointing left and the hyper-defensive right — automatically assumed he must be another of them.

Have politicians stoked the pre-Loughner violence by advocating that citizens pursue “Second Amendment remedies” or be “armed and dangerous”? We don’t know. What’s more disturbing is what Republican and conservative leaders have not said. Their continuing silence during two years of simmering violence has been chilling.
