There should be laws hindering (even some type of penalty) outright lies in our media - be it books, radio, internet, or television. The networks and publishers should be ashamed. The press, or Fourth Estate, is supposed to be a watchdog, a guardian of democracy and truth. It's not that all the networks push these crazy theories and deceptions; it's that they give platforms to the nut-jobs that do.
Two of the latest examples indicating our media is failing mightily: World Net Daily's falsified birth certificate and Michelle Malkin's latest birdcage-liner. Kudos to those groups [hat tip to Media Matters] that stomp out this deceitfulness as soon as they see it.
