What’s going on with young American men? Another mass shooting has led to another round of social and political recriminations. A young man—a “loner” and “adrift,” as usual — seizes a vile cause and attacks innocent people. Amidst the wreckage, we look for reasons that already fit our preconceptions about violence, and we blame racism, guns, unemployment, drugs, a bad family, or whatever else helps us to make sense of the tragedy.

But the truth of the matter is that Dylann Roof (at least from what we know) isn’t that different from so many other young, mostly white men over the past 30 years or so who have lashed out against their society in different ways. Although mass killers understandably seize our imaginations and dominate the media, and not all dysfunctional young males are violent and not all of them gain the publicity they crave. Some are terrorists, others are murderers, and some are merely vandals. A few are traitors and deserters.
