We are sure of representing the majority of the population, of representing the most essential interests of the majority of the Italian people; proletarian violence is thus progressive and cannot be systematic. Your violence is systematic and systematically arbitrary because you represent a minority destined to disappear. We must say to the working population what your government is, how your government conducts itself, to organize against you, to make it ready to defeat you. It is most probable that we too will find ourselves forced to use the same systems as you, but as a transition, occasionally… Certainly: use the same systems as you, with the difference that you represent the minority of the population, while we represent the majority.
