To summarize very shortly my overall view of the protests:
While I wouldn’t quite say it has hit its stride yet, the criticisms of it via the partisan mainstream “left” are ridiculous. When Yglesias and company bitch about “message discipline”, they don’t just mean an overarching message (in fact, depending on your interpretation they either do have one, or have one by deliberately resisting one), they mean institutional constraints of the type that define their preferred method of organizing — which, in case you haven’t noticed, isn’t exactly unscrewing the pooch any time soon. In other words, they envision their own Tea Party: a “movement” of people engaged in pseudo-radical sounding contradictions that lead right back into the arms of convention, sound and fury signifying nothing beyond what already was.
At least when right-wingers bitch about it they have a culture war derived revulsion on their side. What damn excuse do supposed “progressives” have?
