One of the most common criticisms that I have come across about Occupy Wall Street and the Occupy movement in general is that the Occupiers are misguided and that they do not seem to have a message or a real request for change. The CBC's Kevin O'Leary, for example, referred to author Chris Hedges as being a “left-wing nut-bar" because of Hedges' support for and involvement with the movement.
Such comments are common. They are also powerful: not in their reasoning or logic, and not in being well-constructed. They are powerful in their ability to ignore the discussion and dismiss it.
To counter this, the simplest thing to do would be to not be taken in by it. Not being taken in by it, however, requires something else. In this case, that 'something else' is an expansion of how we understand violence.
