Every single "news" network out there skews to a side of the spectrum. How could it not? The news is researched and reported by people, and people have beliefs. We have this insane idea these days that a person can function 100% apart from the basic tenets that form every aspect of how they act.
Yes, FOX skews to the Conservative. But MSNBC skews to the Liberal. Most news networks skew to the liberal these days, actually, simply because most of television culture skews to the liberal. I rectify this by watching both conservative AND liberal programs (despite finding that I am more conservative myself.)
Someone did a study at one point, where they took two groups of people, one that was moderate to liberal, and one that was moderate to conservative. They had these groups discuss hot button issues; abortion, religion, healthcare, birth control, all the stuff that makes people these days cut themselves and wail in the street. They found that just by talking among themselves, the moderate to liberal group started to act and talk more like hardcore communists, while the moderate to conservative group started to act and talk more like hardcore fascists. The consensus was that when you only interact with ideas that you already agree with, you become more entrenched in those ideas.
Human beings are Mammals, and as such we have Basic Mammal Instincts. One such instinct is to act like other people. It's a survival thing; they act like this, they are still alive, therefore if I act like this then I will continue to live. And that's a great instinct, when it comes to how we handle that wild animal, how we handle parenthood, how we react to this exciting new bottle under the sink that has warnings all over it. It doesn't work all that well when we get to the higher-brain society functions.
So my recommendation is to watch equal parts of conservative and liberal things, and try to understand how both sides think. Because honestly, we need both viewpoints if we're to survive as individuals, a society, and a species. Too much of either and things get really bad, really fast.
