Dan the Gnostic
No amount of reason or evidence will ever convince those of this mindset to change their worldview. I cannot say whether or not Dan Rather and CBS News will go down in flames, but you can be certain that should this happen - say, Rather gets fired, CBS's ratings tank, or Viacom's stock goes through the basement - that they will never admit it happened because of lack of integrity, dishonesty, or being blindsided by ideology. Instead, fully expect to hear much gnashing of teeth about the viciousness of the political process, the right-wing hate machine, the evils of the out-of-control internet, and the stupidity of the American people for not understanding the truth.
Count on it.
