Alien Nation

Another angle from Robert Wright:

"Six months ago, police in California pulled over a truck that turned out to contain a rifle, a handgun, a shotgun and body armor. Police learned from the driver — sometime after he opened fire on them — that he was heading for San Francisco, where he planned to kill people at the Tides Foundation. You’ve probably never heard of the Tides Foundation — unless you watch Glenn Beck, who had mentioned it more than two dozen times in the preceding six months, depicting it as part of a communist plot to “infiltrate” our society and seize control of big business.

Note the parallel with Loughner’s case.... But it doesn’t matter who Loughner got the idea from or whether you consider it left wing or right wing. The point is that Americans who wildly depict other Americans as dark conspirators, as the enemy, are in fact increasing the chances, however marginally, that those Americans will be attacked.

In that sense, the emphasis the left is placing on violent rhetoric and imagery is probably misplaced. Sure, calls to violence, explicit or implicit, can have effect. But the more incendiary theme in current discourse is the consignment of Americans to the category of alien, of insidious other. Once Glenn Beck had sufficiently demonized people at the Tides Foundation, actually advocating the violence wasn’t necessary.

By the same token, Palin’s much-discussed cross-hairs map probably isn’t as dangerous as her claim that “socialists” are trying to create “death panels.” If you convince enough people that an enemy of the American way is setting up a system that could kill them, the violent hatred will take care of itself."
