I asked one of these guys what I was supposed to do if some maniac attacked me with a knife, for example (that was after I'd told him I carried a gun for self defense and he had gotten the idea that I was completely nutz).
His answer? "Why, you must run away, of course. And find a policeman!"
Of course, If I didn't run very fast, or had a heart condition, or if the maniac blade-waver was particularly fast I'd be sh*t out of luck, but that didn't seem to enter the equation. The idea seemed to be that defending yourself wouldn't be "orderly" or "permissible", and even immoral. Go figure.
