But guns are not designed to defend or protect you. They do not stop you from getting hurt in anyway. Guns are only designed to inflict damage. So you have chosen to utilize a means of hurting or even killing someone instead of more appropriate defenses that would not be so lethal. Not to mention avoiding the possibility of accidental death.
If someone is coming to kill me or my family (I'm single right now but don't plan on staying that way), I'm not going to stand back and let them do so. What am I supposed to use to prevent them? I'm almost 6 foot tall but weigh next to nothing. I'm not a physically fit person. Even if I was, if the perpetrator was armed, what good what physical fitness do me if he could shoot me at range? :\
As far as accidental death, yeah, it could happen, but that could happen every day to me when I'm driving that 110 mile round trip to work and back, and much more likely out on the highway too than by a gun. Common sense and training with a gun greatly reduces the chance of an accident with one (only point where you intend to shoot, or point at the ground with you finger off the trigger and the safety on, for example).
Gun control, in general, is a horribly flawed notion too. All it does is disarm the law-abiding citizens. The bad guys aren't gonna give a crap whether a firearm is illegal or not. In fact, I'd bet they'd love gun control to be the norm - a disarmed populous is a much easier target.
