"The very concept of "revolutionary violence" is somewhat falsely cast, since most of the violence comes from those who attempt to prevent reform, not from those struggling for reform. By focusing on the violent rebellions of the downtrodden, we overlook the much greater repressive force and violence utilized by the ruling oligarchs to maintain the status quo, including armed attacks against peaceful demonstrations, mass arrests, torture, destruction of opposition organizations, suppression of dissident publications, death squad assassinations, the extermination of whole villages, and the like."
