Chez details how NBC sanitized a wingnut quote about Muslims taking over the country. Of course, here's precisely why:
They're well aware of the accusations of a liberal bias -- very, very tired accusations by now, and ones that are usually leveled with the hope of satisfying a political agenda -- and desperately want to avoid confirming anyone's suspicions. In other words, they overcompensate. Big time. I've seen it happen over and over again; I've sat in meetings where stories were edited severely, watered-down, or killed outright because of the unstated but understood fear that they would validate the time-honored charge that the media are inherently liberal.
Television news clearly isn't reflective of reality or the truth -- not when people who called themselves "journalists" are skewing their coverage simply because they're frightened by drooling hypocrites and chest-thumping maniacs.
