Is Pomposity a Progressive Trait?

A Los Angeles Times guest editorial claims that progressives are pompous. The author ought to know: he claims to be a lefty yet comes off sounding mighty pompous:

I have met this fellow in a score of shapes and sizes, in both genders and over the course of many years, but most frequently at this movie house. And what, exactly, do I mean by "this fellow?" I mean that mix of blithe presumption and fussy preference that so often marks the self-described "progressive." I mean that ostentatiously dissatisfied person whose every gesture displays passive-aggressive tendencies, who gets most of his information from the blogosphere and most of his minimal get-up-and-go from a caffeinated drink prepared to his exacting specifications. I mean a person who belongs, as my wife will gently remind me, to "our tribe," whether I like it or not.

He advises us "progressives" that unless we learn to be modest, humble, self-effacing and decidedly not-pompous (like, for example, Ann Coulter, Rush Limbaugh, Sean Hannity, or Bill O'Reilly, et al.) "seemingly rational people" will be "driven to vote for politicians like Bush."

Maybe he's a mole for the Right!
