The responses of both presidential candidates to the horror in Colorado feel weak to me. They are characteristic of our culture, which treats each of these grostesque acts of mass killing as “tragedies.” The proper response to such an atrocity is rage. It wouldn’t be out of place for the president and the man who hopes to replace him to refer to the shooter as a “monster.” We don’t do that. Instead, we focus on “healing.” We’ve become excellently behaved victims.
