Read “Foucault’s Pendulum”, it is a great novel on how these conspiracies can be self fulfilling or, more often than not, people see what they want. It could be the left, obsessed with the fiction under Bush, have gotten the idea in their mind, and are fulfilling their own prophesy. Or it could be that we have been accused so much of being part of the conspiracy, that it is a thought implanted in our own minds, thus, we see what we want or expect (Rorschach test).
Good points.
