hate encoded in conservative cultural DNA...,

Guardian | In the US, where hate rules at the ballot box, this tragedy has been coming for a long time. The shooting of Gabrielle Giffords may lead to the temporary hibernation of rightwing rage, but it is encoded in conservative DNA.

It was instructive to read elected Republicans' official statements in response to the Gabrielle Giffords shooting for what they did not say. The House Speaker, John Boehner, said: "An attack on one who serves is an attack on all who serve. Acts and threats of violence against public officials have no place in our society. Our prayers are with congresswoman Giffords, her staff, all who were injured and their families. This is a sad day for our country." Arizona Senator John McCain issued the following: "I am horrified by the violent attack on representative Gabrielle Giffords and many other innocent people by a wicked person who has no sense of justice or compassion. I pray for Gabby and the other victims, and for the repose of the souls of the dead and comfort for their families. Whoever did this, whatever their reason, they are a disgrace to Arizona, this country and the human race."

All well and good, and I have no doubt every word is sincere. But you'll note that they are silent on the question of the violent rhetoric that emanates from the rightwing of American society. You don't have to believe that alleged shooter, Jared Loughner, is a card-carrying Tea Party member (he evidently is not) to see some kind of connection between that violent rhetoric and what happened in Arizona on Saturday.

Is he a nut? Of course he's a nut. By definition, anyone who shoots innocent people like that has a screw loose. But nuts come in many varieties. There are some who think Dick Cheney planned 9/11, others who believe the CIA has installed eavesdropping devices in their fillings, and still others who insist they're the reincarnation of Mary Queen of Scots. So what particular type of nut is Loughner? We don't have a full picture yet. But we have enough of one. His coherent ravings included the conviction that the constitution assured him that "you don't have to accept the federalist laws". He called a female classmate who had an abortion a "terrorist".

In sum, he had political ideas, which not everyone does. Many of them (not all, but most) were right wing. He went to considerable expense and trouble to shoot a high-profile Democrat, at point-blank range right through the brain. What else does one need to know? For anyone to attempt to insist that the violent rhetoric so regularly heard in this country had no likely effect on this young man is to enshroud oneself in dishonesty and denial.
