Eventually, the city-dwellers will have the raw numbers, and their natural fear of strangers will drive them to take everyone's guns away. Of course, this will just produce more attractive targets and invite more violent crime, but those facts will not overpower the emotional response one has to being surrounded by strangers, and needing to walk by them every single day.
I don't understand this thinking at all. Fear of strangers should make people want to have a gun of their own. Even if you could take all the guns from all the strangers, strangers are still scary especially to women. Having a gun evens the playing field in a one on one and even if you get jumped by 3-4 guys, a gun at least gives you a fighting chance of making it out alive but most importantly, having the probability of having a gun is really the important part. If guns are mostly illegal then a criminal doesn't really have to worry about being shot. On the other hand, if it's fairly easy to get a handgun, even if only 10% of women do, this gives herd protection to all the rest of the women who don't carry a gun because now there is a 1 in 10 chance of getting shot if you try to attack someone versus a 1 in 1000 or greater chance if guns were outlawed.
