Stephen Budiansky expands on his earlier post:

For as long as I can remember, I have heard conservatives blaming everything that is wrong in the universe, from violent crime to declining test scores to teen pregnancy to rude children to declining patriotism to probably athlete's foot  . . . upon Dr. Spock, Hollywood liberals, the abolition of prayer in school, Bill Clinton, the "liberal 1960s," the teaching of evolution in other words, upon symbols, rhetoric, cultural norms, and the values expressed by political and media leaders. Yet from the moment when someone gets a gun in their hands, apparently, society ceases to have any influence whatsoever on the outcome and individual responsibility takes hold 100%. Something is driving the tripling of death threats against congressmen (and the concomitant rise in threats against Federal judges and other villains of the right, from Forest Service rangers to climate scientists) and it isn't the sunspot cycle.
