There is a difference, of course, between force and violence. Force must be used if change is to occur at all, wether that is blocking an intersection or hitting a baseball, force is the power that we exert onto this world. The problem, in my view, arises when force is exerted from a position of power and prviliege in order to keep another down. This is violence. Violence, not only in the physical sense, degrades its victim AND its perpetrator. I am not against the use of force, rather the use of violence.
