I was really trying to avoid this but there have been so many careless mischaracterizations bandied about, I feel compelled to respond.
Armed citizens, by and large, do not "live in fear"...at least no more so than the anyone else. I'm one of them and I live a life much like others here. I don't think I'm Rambo...or a super cop...or a vigilante...nor do I have any other macho fantasy self image. It's not a fetish object. It's a tool. I have fire extinguishers in my home...I have a first aid kit and winter survival gear in my truck...and I carry a firearm for personal defense. None of that makes me anything more than a guy trying to prudently look out for himself and his loved ones.
It's not about us "living in dystopian caveman dog eat dog world." It doesn't have to be bad all over to be really bad at just one moment, in just one place. I live in a great city in a great state and wouldn't live anywhere else. But like any other community, we have our problems here and there. Bad things do happen to good people and it isn't always on "that side of town".
We don't always take precautions because an undesired event is likely. Sometimes, we take precautions because the consequences of that event, no matter how remote the possibility, are grave. If I carry my firearm today and don't need it...yah-freakin'-hoo. I'll gladly live the rest of my life never having to use it for self defense. But if I do ever need it...I'm really going to need it. I know people who had the need, had the firearm, and I'm glad they're still here today.
Now, if you're one of those folks with philosophies about cutting violence off at the source, not answering violence with violence, etc...more power to you. Good luck. I mean that. Just don't ask us to forego our personal defense for the sake of your social experiment. And while you're at it, please spare us the uninformed stereotypes about gun owners gleaned from too many movies, television, news media, or perhaps your own personal prejudices. It gets old. Quick.
