THE NEW YORK TIMES' BILL KELLER thinks Fox News is biased. And then there's this:

We have too often been condescending to those who don’t share our secular urban vantage point. We are too easily seduced by access. We can be credulous. (It’s also true that we have sometimes been too evenhanded, giving equal time to arguments that fail a simple fact-check.) But we try to live by a code, a discipline, that tells us to set aside our personal biases, to test not only facts but the way they add up, to seek out the dissenters and let them make their best case, to show our work. We write unsparing articles about public figures of every stripe — even, sometimes, about ourselves.
