Just as you are not required to give up your gun, people who feel uncomfortable around them are not required to carry them. It should never be a requirement of feeling secure to have to carry a gun.
Now, speaking as a good Southern girl whose grandfather taught her how to shoot when she was eight, I still don’t feel 100% comfortable around guns. I can fire one, I can (usually; I’m out of practice) load one. I could probably hit a person if I aimed at them.
At the moment, I also live in a house with a very overinquisitive two-year-old who has an impressive proclivity for opening doors and drawers and such. She’s clever enough to turn computers on and off, change channels, and take DVDs out of the player and put music CDs in. I have no doubt that she could do some real damage with a loaded gun. So we keep the only one we have (small, black, menacing-looking) locked in the handy-dandy gun cabinet next to the back door. Even if she managed to clamber onto the cabinet (and while she is very agile, that would take more strength than even she has), she is not strong enough to open the latch (tricky for we adult types) and continue standing on the shelfy bit. So we’re fairly confident that she’ll be out of the gun cabinet for at least another two or three feet of growth.
Now, the only gun we have is a pellet gun (looks like a pistol, it’s a glorified BB gun, good only for scaring the squirrels and neighborhood dogs away, but in the dark it’s surprisingly gun-shaped) and the selfsame gun cabinet is filled with knives and Renfair swords and such. We have an impressive show of cutlery in there, and some of it could actually conceivably hold up if you were trying to defend yourself with it. Personally, I’d love to be a fly on the wall if a burglar came in at 2 am, thinking no one would be awake, and being greeted by a large, 6-foot plus menacing-looking bald man with a sword. 
As for women and self-defense: if you feel uncomfortable with a gun, I understand. Take self-defense classes instead. You won’t be caught without your arms and legs, and there’s a lot you can do in order to disable your attacker and get away. Now, the women who were attacked in their own homes were caught at a real disadvantage…this is why, if I feel particularly unsafe, I sleep with a steak knife at close hand.
And as for guns not being made for killing: Guns can be used for sharpshooting and target practice. I did not buy a bow and arrow for use in killing people or animals; I use it for target practice, for building strength and hand-eye coordination. But a bow’s purpose, that for which it was created, is for hunting and for killing. There would be no need for the item without those purposes. The same goes for a gun – it can be used for hunting, for defense, or for sharpshooting practice, but its primary purpose is for one of the first two. And since we are not talking about buying guns for target practice, how can you say these guns are not meant for killing? I guess you can say they’re meant for intimidation, but someone here’s already said that they should be used to kill a potential assailant, not merely to scare him off.
