It is if you know anything about the civil rights movement!
I'm not evaluating the relative merits of each "cause".
I believe income inequality and unemployment are very serious, and the fact that our political system is bought and sold outright is at least as serious as civil rights violations in the 50s and 60s. I'm talking about comparing the seriousness of the protestors. OWS has no leader. It has no policy recommendations or demands. It has become overrun with the homeless and drug users, and has attacted a criminal element in several of it's cities.
I've been to OccupyChicago a few times, and it's really just a laundry list of various far left complaints, just most of the big "left" protests over the past 5 years. If this is really about inequality, I better not see any signs about pot....but I did.
