I know I shouldn't be surprised that a shooting incident has brought forth such an outpouring of stupidity and intellectual dishonesty, but it is surprising in its intensity. Here's what we know so far, from what I've read. The shooter was an unstable individual with a penchant for conspiracy theories, and a specific grudge against Rep. Gabrielle Giffords. That's really all we know for sure. But that hasn't stopped an amazing eruption of complete nonsense, mostly from the left and its enablers in the media. The ridiculous speculation that violent political imagery -- which is nothing new and no more intense than it has been in the past -- is somehow responsible for this incident, is actually being seriously discussed, instead of receiving the derisive laughter it deserves. People seething with intense hatred for Sarah Palin, who know full-well she had no connection whatsoever to this incident, have shamelessly tried to smear her with responsibility. Then there are the usual idiots who pretend that if we just passed another gun law, somehow these incidents could be avoided.
Unless some sort of multi-person conspiracy is unearthed, or a clear motivating ideology, as in the case of radical Islamists, this incident can be best explained by the same explanation that applies to most such one-person shooting sprees: nuts do crazy things. When you have someone whose outlook on life and reality is so out of whack that he's willing to kill a bunch of random people just to get someone he's formed a grudge against, there's no telling what might set him off. The idea, in the absence of any evidence, that he was somehow motivated by a politician or media figure you don't particularly like, even though those figures aren't actually calling for any violence, is utterly ludicrous. I believe most of the people pushing such theories know that, and are just behaving like the intellectually-dishonest hacks they are.
