While I support the right, I have no interest whatsoever in guns, and the only arms I bare are at the beach. I'm puzzled by the fascination so many people have for guns. When you come right down to it, they're pretty useless. For personal defense, I'd have to drag this chunk of heavy metal around with me everywhere I go, in the extremely unlikely event of ever needing to use it. In the many decades I've been an adult, I cannot think of a single instance where a gun would come in handy.
It's just as useless for home defense. It's only going to work if I happen to be at home, which is the least likely time anyone is going to break in. If someone does break in when I'm gone, the gun is probably on their list of items to steal. I don't want to leave it just laying around, loaded, which means a safe place to keep it--somewhere where kids don't have access to it. So, if some evil-doer bursts through the door, I'll yell at my wife, "Quick--open the gun safe, take off the trigger lock, and load the weapon!"
Also, I wouldn't want a cheap gun. A good one will cost hundreds of dollars. Not to mention the gun safe, etc. For that money, I could buy a good alarm system and locks. And then there's the gun training and regular target practice, since the skill degrades rather quickly. That's time I could be doing something I enjoy.
