I am 57 years old,,, I learned when I was 17, (forty years ago) the rules of fighting. The first rule is to win. If the fight is not worth any action you have to do to win, you should walk away. The second rule is,,, Make sure you are always better armed than your opponent. There is no third rule, if you feel a need for a third rule, you should read the first rule again, until you understand it.
I am pleased that he can kick and punch his way out of a knife fight, or a gun fight, or a home burglary. At my age I have decided that if god meant for me to touch my toes, he would have moved them up to my knees. If he meant for me to be a victim, he would not have made guns. I have five grandkids, and I am pleased that my daughters do not have to kick and punch to defend themselves, and my grandkids.
I do not care that his choice is not to arm himself. My choice, and the choice of each and every one of us should not require his approval.
I do not mind that he wants to "fight fair", personally I think that is an oxymoron. fight, and fair, they conflict with each other at the very base of meanings.
