If there are sound reasons or bases for the points you demand, then there is no need for violence. On the other hand, when there is no sound reason that concessions should be made to you but mainly your own desire, then reason cannot work and you have to rely on force. Thus using force is not a sign of strength but rather a sign of weakness.
