I'm from the state involved and I speak with at least one person presently residing in the state every day. To say that the area is unusually polarized is true. It just is. And the politics there have been aggressively ugly.
I understand that it is not the case that he's what we think of as a prototypical tea partier but I think the other side is pushing too far in saying that there is no possible way there's an influence or an undercurrent involved. I mentioned earlier that there's some recognizable strands, particularly in relation to his beliefs regarding hard backed currency, conspiracy theories, and exotic interpretations of specific sections of the Constitution. In an effort to demonize those who said there was a link I've seen literally no discussion from the right side, here or anywhere else, about these parallels.
Here's the thing: political violence is not a random occurrence except in the rarest of instances. Loughner was not trying impress Jodie Foster. He had specific beliefs and went after Giffords, at least in part because she's a government representative. The track record on him having paranoid ramblings about government control of his grammar and, by extension (according to him), his very thoughts is irrefutable. (I'm coming around to the idea this was probably influenced by Derrida, but that's another discussion).
That the threat of political violence against government officials, particularly those on the left, has escalated dramatically during a period of time where one side's rhetoric has tended towards the idea that a Democratic-Party controlled government is, in and of itself, illegitimate and the enemy of the people is unlikely to be a coincidence. When Steve King empathizes with a guy who runs his plane into an IRS building, the message is that the government is your enemy. When Eric Cantor emonizes Democrats for even mentioning they're subject to unprecedented levels of death threats, the implicit message is that those threats are acceptable. Those expectations that some level of political violence was inevitable have been building for at least 10 months since it was revealed that Democratic congresspersons were subject to very high threat levels.
Some want this to be a teachable moment. That so many were unsurprised something like this happened says almost as much about the climate as if he had actually been purely motivated by right-wing politics. This is an instance where overheated speech creates expectations and those expectations inform how we process events. The other side is trying their damnedest to say "not only do we learn nothing, but we refuse to acknowledge we need to learn anything." That removes what little bit of optimism I had about how this would shake out in the medium to long term.
Mental illness doesn't express itself in a vacuum. Context does matter, and we have strands and pieces that indicate Loughner was at least cognizant of particular messages portrayed by one side of the aisle. That he was more nut than political agent doesn't absolve one side entirely. But that's the way it looks like things are going to shake out in our consensus-based group think.
Quite unconvincing.
Why would anyone be surprised this happened? Things like this always happen.
Hard backed currency advocates are just as left as they are right. You're argument hinges on this blanket notion that the far-right--who have absolutely no connection to the conservative right or tea party right other than the word right--have a monopoly on "hard backed currency, conspiracy theories, and exotic interpretations of specific sections of the Constitution". Talk about group-think at its best.
"Mental illness doesn't express itself in a vacuum" is as laughable a statement as they come. Have you read anything about the various mental disorders taking over reality?
Maybe you should focus a little more attention on understanding both sides involved and less time subtly attacking one side for ideological reasons. Do you want an argument on how your support of forceful policy causes the restlessness and anger that, according to your pet theory, is at least partially responsible for this violence?
