Yes, the piece is funny, but it makes a serious point. From a piece on my blog, DOUBLE TOOTHPICKS entitled RatherGate Casualty: TRUTH:

After they take leave of all conscience and doff the weighty burden of absolute truth, what will prevent the MSM from making up anything they want to 'prove' anything they want? Anachronisms, you say? "Why, anachronisms are mere shackles to puritan notions of truth, from which the more enlightened among us have been freed." ... I predict that once the MSM has drunk deeply from Proud Dan's vintage cask of Bulverism, and sloughs off the oh-so restrictive burden of proof, the real casualty in this war of words will be Truth.
 

Ridicule in the LA Times is a sure sign that Dan Blather has lost the protection of the leftist cocoon. You're on your own in deep space, Dan, without a spaceship, and your oxygen's running low!
