WHY DOES EVIL MAKE LIBERALS STUPID?

In the aftermath of the Boston Marathon bombing, we are suffering through the inevitable period of liberal hand-wringing. Liberals can’t help themselves: while normal people are reviling the bombers, celebrating their capture or death, and debating measures that can be taken to prevent future atrocities, liberals’ thinking (if you can call it that) goes in a different direction. Liberals call for understanding; tell the rest of us we don’t realize how complexmass murder is; recommend introspection (But why? I didn’t do it.); and warn against various forms of overreaction to the latest terrorist outrage. The reality of evil, a constant in human affairs for millennia, renders liberals not speechless–that would be too much to hope for–but incoherent.
