I don't think you're effectively rebutting my larger point, which is that these protesters represent themselves as being of one population, when they are in fact of another. Certainly, if I change my statement to "some port workers" were economically damaged by the protest, purportedly on their behalf, in which they did not participate or call for, the point remains. Regarding the "convenient mis-characterization" -- my girlfriend worked in a major union for five years, specifically in the communications department; I know very well how to read statements made by, and on behalf of, union leaders. The kind of tension and political tiptoeing I described certainly exists.
The mere fact that we can point to two statements, one expressing support for Occupy, and one denouncing a specific Occupy action, by definition means that there is a conflict in strategy and tactics.
Now, I will grant that this is all based on my opinion and observation -- none of it is empirical or measured. So what? Supply some measurements if you think that my opinion is illegitimate. Tell me what percentage of Occupiers are actually from traditionally poor background -- those who suffer systemic disenfranchisement, a lack of role models, have insufficient access to education -- you know, the people who they claim to represent. If this is such a diverse movement of the working poor, go ahead and let me know how the demographics of self-identified Occupiers compares to that of East Oakland (the poorest neighborhood in Oakland.) Shit, speaking of diversity: I would be surprised to learn if even a single percentage of them were multilingual!
I'm all for advocating on behalf of those who have been systematically locked out of opportunity, who have never been able to access the things we all take for granted, which have made it possible for us to be so successful. The people I see at Occupy events are poor, but it doesn't seem to me that it's for a for lack of access. They are bitching, basically, because the opportunities for very well privileged slackers to get by decently without putting in too much effort have all dried up. The rest of us -- poor and working rich -- are busting our asses off.
Happy to be proven wrong, but these are my observations, and yes my biases too.
