>>We never saw the kind of violence, filth and bad behavior that characterized the left during "Occupy Wall Street" at any Tea Party event.

In fairness, the concept of camping out in the local park in a good cause is more likely to attract opportunist but otherwise uninvolved undesirables than a Tea Party rally at the Town Hall. I suppose you could ask whether or how Occupy organizers can prevent troublemakers joining the throng and conducting mayhem behind a moral figleaf. Seems to me the real story was general restraint by authorities who seemed to prefer to wait it out than risking making a mistake coming down hard and fast on people in a camp in a public park.

In any case, tribalism as described by Tamar is making some people very rich while messing up what ought to be the most desirable nation on earth. So who cares what splinter group was the most antisocial. Unless you can persuade politicians to focus on things that matter, the US risks repeating the UK slide from greatness while the Chinese or Indians scoop up the dropped baton and run with it.
