This response was understandable. It’s important to tamp down vengeful hatreds in moments of passion. But it was also patronizing. Public commentators assumed the air of kindergarten teachers who had to protect their children from thinking certain impermissible and intolerant thoughts. If public commentary wasn’t carefully policed, the assumption seemed to be, then the great mass of unwashed yahoos in Middle America would go off on a racist rampage.

Worse, it absolved Hasan — before the real evidence was in — of his responsibility. He didn’t have the choice to be lonely or unhappy. But he did have a choice over what story to build out of those circumstances. And evidence is now mounting to suggest he chose the extremist War on Islam narrative that so often leads to murderous results.

The conversation in the first few days after the massacre was well intentioned, but it suggested a willful flight from reality. It ignored the fact that the war narrative of the struggle against Islam is the central feature of American foreign policy. It ignored the fact that this narrative can be embraced by a self-radicalizing individual in the U.S. as much as by groups in Tehran, Gaza or Kandahar.

It denied, before the evidence was in, the possibility of evil.
