Well there is no doubt in my mind that the "culture wars" have infected the news networks. That being said, I believe that news, like history (written by the victors), is always slanted. Not necessarily for just the Right or the Left, but for whatever the ideoligy of the journalist is. This ideoligiy seems to usually be composed of money and ratings. In a nutshell, news has become entertainment.

I personally believe that all news organizations should be liberal - not liberal in the sense of left-leaning - not politically liberal. But liberal in what is reported and how detailed the report is. Liberal in an impartial way. This way, a topic can be reported as well as it's impacts positive or negative and to whom.
