As a martial artist for over 25 years, I have always viewed myself as a sheepdog, and it has nothing to do with whatever weapon I'm carrying, or not carrying. I teach my students the same attitude.
Fortunately our society has many more people who will look out for others, and extend themselves beyond the primitive, the tribal attitude of "As long as me or mine are not threatened, it's not my problem."
Nutnfancy always tempers his comments by emphasizing that you do what's legal in your area, and what's logical to you. I actually like the long-windedness, the detail is fantastic.
