Oddly enough I've met violence with violence many times, and I'm still here. If I'd cowered and done nothing, I'm pretty sure I'd be dead.
I know quite a few more people who can say the same.
This biz about "John Wayne fantasies" is a strawman argument, not to mention insulting. Quite a few of us have used weapons in real life to prevent or stop a crime, and your belittling of that is quite offensive.
