An acquaintence of mine teaches rape prevention. He offered concealed carry as a solution since he lives in a concealed carry state. One student insisted that she could never shoot a potential rapist. He asked his class who wouldn't shoot a rapist and maybe 1/3rd to half the class raised their hands. He then asked who would shoot someone wanting to rape their children and all but one or two raise their hands. While I'll agree that some people are born victims, I do not think it is a very large number.
Finally, I disagree with your usage of the term 'meek'. 'Meekness' does not equate wimpiness. Many of the quite, meek people I know are quite tough, but sometimes the biggest 'tough guys' are in reality the biggest wimps.
Sorry, I disagree with your friend. A lot of people who think they could shoot an intruder find they can't. Not everyone is cut out for physical conflict, armed or unarmed, period. Nothing you can say will ever change my mind on this, as I've come to this conclusion after years of first had experience.
