I was raised being told that there is no good reason for an honest person, who is not law enforcement, to ever shoot a gun, let alone own one, except hunters, maybe, sometimes, if they really have to. I never agreed with that line of thought, but, since I was never around guns, I was not comfortable with them simply because I knew that I had no clue how to handle them safely.
After moving to Arizona and going shooting with friends a few times, and just generally having guns around, I became far more comfortable with them and made a point of learning how to properly handle and shoot them. I did *NOT* go out and just buy a gun as soon as I decided I wanted a gun. I went out with those who I knew were excellent, reliable, sources of accurate information, and who could help make sure that I was making the right choices (there are countless different guns available and there is no 1 right choice for what to get - there are too many factors involved).
I also went out shooting very regularly, both at indoor and outdoor ranges, shooting friends guns, to make sure that I was comfortable with the types of guns I was considering buying and was able to aim well enough to meet the expectations that I had for myself. Then and only then did I start looking at what to buy. Once I bought my gun, I again went out quite a bit to make sure that I was very comfortable with it and knew exactly how it handles.
As Chris and Tom said, a gun is a tool. For any tool, you need to know how to use it safely and you need to practice to make sure you do know how to use it safely. There are several knowledgable, trustworthy people on this forum who have excellent gun collections who can help you narrow down what you want and Caswells (Bridger's store) is great in that (among other things) they have gun rentals for the indoor range and you can change out the gun as often as you like while you're there.
Try going out shooting (make sure it's with someone who is very well versed in the proper ways to do things so you arne't getting bad info) and see what you think when you're actually out there and seeing/participating in responsible gun handling & use and you'll see that it's really not as frightening a concept as you had convinced yourself it was.
And, as a side note, I've seen Tom taking his kids out shooting - his kids KNOW safe gun practices. He has taught them well and I would take advice on how to have kids and guns in the same house any day - he's doing it right. When I was out at the range with them, I was not at all concerned about the fact that there was a 3 year old out there with us - because that 3 year old knew exactly what was expected when there were firearms around.
