"Occupy" shutting down the ports (update)

Um, excuse me? Why? Why are you doing this? Why would you shut down the shipping ports on the West Coast? What does that prove? What does that do? What does that do for your movement? I'm with you on taking back the nation from the corporations and the wealthy, especially by killing "campaign contributions" to politicians but this? Even the unions are against this and they're on your side. What are you doing? Do you even know? What does this gain you except bad press? I don't get it. Someone explain it to me, please. It makes no sense. It seems to be action for action's sake, with no positive side to it.
