Regardless of why the shooter killed at least 6 people in Tucson, the fact remains that the politics of this country, primarily on the right, are filled with hate and violent language. George Packer summarizes it well in the New Yorker:

…for the past two years, many conservative leaders, activists, and media figures have made a habit of trying to delegitimize their political opponents. Not just arguing against their opponents, but doing everything possible to turn them into enemies of the country and cast them out beyond the pale. Instead of “soft on defense,” one routinely hears the words “treason” and “traitor.” The President isn’t a big-government liberal—he’s a socialist who wants to impose tyranny. He’s also, according to a minority of Republicans, including elected officials, an impostor. Even the reading of the Constitution on the first day of the 112th Congress was conceived as an assault on the legitimacy of the Democratic Administration and Congress.

This relentlessly hostile rhetoric has become standard issue on the right. (On the left it appears in anonymous comment threads, not congressional speeches and national T.V. programs.) And it has gone almost entirely uncriticized by Republican leaders. Partisan media encourages it, while the mainstream media finds it titillating and airs it, often without comment, so that the gradual effect is to desensitize even people to whom the rhetoric is repellent. We’ve all grown so used to it over the past couple of years that it took the shock of an assassination attempt to show us the ugliness to which our politics has sunk.

Oh, and the backpedaling continues in Palin country. Palin aides are calling the cross-hairs on the Palin targeted districts flyer mere “surveyor’s symbol.”

“We have nothing whatsoever to do with this,” Palin aide. Rebecca Mansour told the talk radio host Tammy Bruce in an interview.  ”We never ever, ever intended it to be gun sights. It was simply cross-hairs like you’d see on maps,” she said, suggesting that it is a “surveyor’s symbol.”

But Palin herself referred to the marks as “bullseye” icons.
