Having my neighbor shot by a would-be home invasion robber followed by the other neighbor shooting at his girlfriend in the street the following year (22 feet in front of me), I get the impulse to protect oneself. (Didn't happen in WW--prompted the move though!) I have somewhere in storage my ggrandfather's pistol from when he was a sheriff in Yankton SD in the 1880's, most of my relatives have been in the military and so I have grown up with and around guns. Guns do not freak me out. . . I think edssds has some really good points to consider.
(And Jules.)
And for heaven's sake, if there is a child in the house with a gun, use a lock and wear the key around your neck. If you can train yourself to brush your teeth when you get up and go to bed, you can train yourself to lock and unlock your gun as you keep it in your nightstand, under your pillow, etc.
