I think it's incredibly dangerous to believe your news-source of choice is unbiased. It's also IMO sort of intellectually lazy to believe one side of the story...

If you're at all interested, the PEW study on this stuff from earlier this year is an interesting read:

You can snip interesting sound bites all day from it, but to me the most interesting thing is how CNN and print media roughly DOUBLED on neutral/balanced stories vs. 4 years ago. Fox and MSNBC instead increased their bias vs. 4 years ago.

In the face of that study, and your general sense of the modern media environment, I'm not sure how can you reasonably assert there's not significant bias in Fox's news coverage? I certainly wouldn't assert that about MSNBC (which I've probably spent a collective 2 hours watching in my life, so I admit I'm under-informed on)
