"If there are sound reasons or bases for the points you demand, then there is no need to use 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.
Yes, I absolutely agree. Anger is a sign of weakness. Wonderful quote by the Dalai Lama.
