While I see what you're getting at -- why be upset over someone's opinion, which is pretty much my philosophy 99% of the time -- but there's one problem:
Kurtz, and others like him, help direct our nation's political discourse.
He, Limbaugh, Hannity, Beck, et al, manage to get things into the discussion that, quite frankly, have no business being there in the first place (see: Kerry, John, and his joke) ... they play fast and loose with the facts ... the serve as textbook examples of hypocrisy ... and they project their insecurities onto everyone else so much that they may very well turn into PowerPoint presentations.
If they were just fringe players with little to no audience (like, say, my old blog) then yeah, who cares?
But they're not.
They are widely read, and keep getting their buttugly visages on the teevee and their cackling voices on the AM dial. Politicians take note and repeat their false claims (the "slow bleed" term comes to mind). And, for reasons I still can't figure out, manage to frame the issues in ways that often do not match reality.
So it's imperative that Glenn Greenwald, MediaMatters, Kevin Drum, et al, point out these issues. Not so that the left can turn around and do the same thing (I'd like to think we're a bit above that), but so that the public can know the truth ... so that our national discussions can focus on real policies and getting things done, rather than on personal attacks and petty issues .... and so that we, as a nation, can move forward together.
Of course, I could be wrong ...
