But as far as what we should "rally around," I think your question is missing the point. It isn't that the NYT, Slashdot, Fox, are 100% full of lies. There's obviously some truth/stories in there.

And it's entirely possible that Democracy Now (not that I think this is at all likely) will be subverted by corporate goons tomorrow. So it's not like DN is infallible or anything. You just have to use your best judgment about how and where you consume news. As soon as you trust anyone else to carry out that task for you, you risk being deceived.
