The word violence implies brutality and barbarity. We should never embrace violence, however; Force is a tool to be used for the defense of our being and our ideals. Every pragmatic and self-reliant adult should recognize the importance of being able to protect yourself and your family with the use of Force.
But It takes true strength and wisdom to resist resorting to violence, because perpetrating violence on others only begets more retaliatory violence in the world. We use Force to punish those among us that bring would violence on others.
Those advocating the use of violence are at best misguided and immature, and at worst are deceptive agents of chaos sowing seeds of disunity and hate. They are our enemy, we know they are our enemy, and when all is said and done those that bring malevolence into the world will reap what they've sown.
