By all means, condemn the hateful rhetoric that has poured so much poison into our political discourse. The crazies don’t kill in a vacuum, and the vilest of our political leaders and commentators deserve to be called to account for their demagoguery and the danger that comes with it. But that’s the easy part.

If we want to reverse the flood tide of killing in this country, we’ll have to do a hell of a lot more than bad-mouth a few sorry politicians and lame-brained talking heads. We need to face up to the fact that this is an insanely violent society. The vitriol that has become an integral part of our political rhetoric, most egregiously from the right, is just one of the myriad contributing factors in a society saturated in blood.

According to the Brady Campaign to Prevent Gun Violence, more than a million people have been killed with guns in the United States since 1968, when Robert Kennedy and the Rev. Dr. Martin Luther King Jr. were killed. That figure includes suicides and accidental deaths. But homicides, deliberate killings, are a perennial scourge, and not just with guns.

Excluding the people killed in the terror attacks of Sept. 11, 2001, more than 150,000 Americans have been murdered since the beginning of the 21st century. This endlessly proliferating parade of death, which does not spare women or children, ought to make our knees go weak. But we never even notice most of the killings. Homicide is white noise in this society.
