In the wake of any mass or school shooting that occurs in America, which pretty much means most of the time that exists, everyone immediately runs to their preferred corners to blame their preferred target for the latest tragedy. I've pointed this out as often as I can, but the truth is that both gun violence and the incidence of mass shootings in America is a terribly complicated subject that deserves all the nuance and sober-thinking it could possibly be afforded. But, since this is America we're talking about, we tend to do the exact opposite and instead pick a single target and heap as much blame as we can on it. It's guns that's the problems. Or it's violent movies. Or video games. Those are the typical targets, and they have been for some time. Meanwhile, the shootings continue, nothing is done, and on it goes.

House Rep. Diane Black of Tennessee knows why this is. We've had the wrong target all along. The real cause of school shootings is porn.
