But much of this progressive criticism consists of relatively (ostensibly) well-intentioned tactical and organizational critiques of the protests: there wasn't a clear unified message; it lacked a coherent media strategy; the neo-hippie participants were too off-putting to Middle America; the resulting police brutality overwhelmed the message, etc. etc. That's the high-minded form which most progressive scorn for the protests took: it's just not professionally organized or effective.
Some of these critiques are ludicrous. Does anyone really not know what the basic message is of this protest: that Wall Street is oozing corruption and criminality and its unrestrained political power -- in the form of crony capitalism and ownership of political institutions -- is destroying financial security for everyone else? Beyond that, criticizing protesters for the prominence of police brutality stories is pure victim-blaming (and, independently, having police brutality highlighted is its own benefit).
Most importantly, very few protest movements enjoy perfect clarity about tactics or command widespread support when they begin; they're designed to spark conversation, raise awareness, attract others to the cause, and build those structural planks as they grow and develop. Dismissing these incipient protests because they lack fully developed, sophisticated professionalization is akin to pronouncing a three-year-old child worthless because he can't read Schopenhauer: those who are actually interested in helping it develop will work toward improving those deficiencies, not harp on them in order to belittle its worth.
That said, some of these organizational/tactical critiques are valid enough as far as they go; the protests could probably be more effective with some more imaginative, concerted and savvy organizational strategies. The problem is these criticisms don't go very far -- at all.
