We’re in the situation we’re in because people are ignorant and easily deluded.  I refer to rampage shooters and terrorists both, exploited and manipulated into committing their ghastly acts, as well as to you the reader.  It’s an unpleasant truth, but in order to combat it, we’ve prepared a short summary of some history that everyone really ought to know.  The diligent reader may learn how they are being manipulated and by whom — and perhaps even do a little independent thinking.

It’s a bit of a reach, I know, but I have faith in you.
