The lessons of the tragedy in Colorado seem blindingly obvious: Guns are a scourge on our society. They should not be legal. Apparently saying this amounts to “politicizing,” but you know what? This is already about politics. Our broken system is such that no national figure from either party wants to touch gun control. That wasn’t always the case, but it never seems to change these days, no matter how many horrors we witness. It’s sad, but it’s also infuriating, and this is exactly the time to talk about it.
