I can't say I'm a fan of Fox, but I will say the majority of the people like to make it out to be a lot worse than it actually is (I'm guessing the most they've ever actually seen of the station are a select few clips regarding Mass Effect). I have a mother who watches it just about every day, believe me, I see quite a bit of it.
Some of the hate they get is totally warranted - I think Obama is the worst President in the history of the United States, and I'll be the first to say they take to ragging on the guy way too often. In addition, the Republican Party is never, ever responsible for things they're totally responsible for, the "Progressive Agenda" is what's single-highhandedly destroying America, and, of course, video games are the devil's work.
But on the other hand, they do generally make an effort to present both sides of an argument, sometimes even fairly (sometimes), and in all honesty Glenn Beck isn't quite the extremist he's often made out to be (I'm no fan of his, but having seen more of him than most people here, he falls more toward the small-government grassroots movement than the typical right-wing zealots like Bachmann or Perry do).
To be fair, this forum strikes me as being as left wing as Fox is right wing half the time. A lot of you do the same thing they often do: you talk about things you don't know about as if you knew about it, and your mind is already made up before the discussion has even begun. Not any worse, but exactly an improvement.
TL;DR = Fox isn't great, but isn't quite the EEEEVIL news station it's made out to me.
