I've always heard the quote "...rough men stand ready to visit violence on those who would do us harm." I think it makes a moral difference if someone is going to be violent on my behalf or execute that violence in my defense. George from East Bridgewater has a point - there is also great honor in humility. Knowing I can kick your ass if you try to invade my country and arrogantly broadcasting it on a bumper sticker or T-shirt is 2 different things.
