Cause and Effect

I've read some stuff by Willaim Raspberry, and it's usually pretty good. But today's article is almost as misguided as it is shrill. Raspberry is upset with Fox News and sees grave danger in their popularity.
His main fear:

The ... far more dangerous... effect is that it threatens to destroy public confidence in all news. ...I think the plan is not so much to convince the public that its particular view is correct but rather to sell the notion that what FNC presents is just another set of biases, no worse (and for some, a good deal better) than the biases that routinely drive the presentation of the news on ABC, CBS or NBC -- and, by extension, the major newspapers.

Mr. Raspberry is afraid that if journalists are seen as partisan or agenda driven, they won't be taken seriously as "seekers of truth." And he's right.
The problem is Willie, you journalists might see yourselves as seekers of truth, but you promote yourselves as "sources of truth." (see next paragraph) Your arragance, the idea that you alone have the corner on truth, that you should be the "gatekeepers" of the news, makes you look like midevil clergy, trying to keep the Bible away from the masses. Really you're just trying to keep yourselves in power.
Fox News isn't causing the lack of respect for your honored profession. They're just taking advantage of your mistakes. You seem to ignore the CBS hit-pieces and the documented liberal leanings of most journalists. If you want someone to blame for your loss of credibility, don't look too far.
