I don't personally believe in gun ownership. But I do not feel the need to infringe on those who do own guns. I have expressed this opinion openly and I have always received the same inquiry..... What happens when bad things happen?
Home invasion? I have enough hand to hand skills to really hurt the guy. Uncle Sam and I spent a summer or 2 together and he taught me a lot of cool things I can do with my hands and things around me to really hurt people.
Doomsday? I have enough skill to acquire a weapon. I got neighbors who own guns.. So if worse comes to worse, I can eliminate one of them and acquire their guns.
Zombie Apocalypse? I got crowbars, baseball bats, and an ax. And according to the video games I see, the streets are always littered with Guns and Ammo and also health packs. So I think I am good there. =)
