Sorry Virginia, there is no liberal media

I'm still mulling over the demise of common courtesy today and Peter Daou's post, throwing down the gauntlet resonates with me. He has this to say to the wingers who are the blaming the media for Cheney's mess, .

So here's my challenge to rightwing bloggers who assail the media for liberal bias (and to journalists who think it's all a he-said-she-said pissing match): Back up your claims. With concrete examples of bias. And without the tautological crutch that any story critical of the administration is proof of liberal bias.

Peter backs up his thesis that the media in reality is tilted to the right, in spades. Of course he has facts to work with, so he makes his points without taunting or gratuitous mockery. I'll be surprised if he receives the same courtesy in reply.
