I will concede that attempts to curtail freedom of speech on campus comes mostly from the left. The current political climate leaves the right on campus little to protest.  There is however a long history of right wing violence in America to suppress dissent on both economic and social matters.  

If one does not want to live in an inverted totalitarian state which America has become with no chance for change then there is going to be push back.  Unfortunately a few see violence and disruption as legitimate means of dissent no matter how wrong headed.

And, yes, the 99% should work to find common ground however when too much money is allowed to foster  simplistic,unrealistic solutions to complex problems many respond not realizing that they are working against their best interests.  Money is just another form of violence manifested in the promotion of policies inimical to the public good.
