I grew up with guns. I have early memories of going squirrel hunting with my father and grandfather. My friends were no different. I never much thought about it. I don't recall anyone locking up gun racks - we didn't know anyone with gun safes.
The United States has been at war, almost constantly. We are a culture of people who have readily taken up guns. Good? Bad? Just the way it is. But, if you have learned to enjoy shooting and enjoy guns why would you not be fascinated with them. I have a few guns that, as far as self defense, aren't much better than a BFR, but I keep them and clean them and shoot them from time to time.
