A friend of mine owns a couple of guns, but he never uses them for stuff like killing people or other creatures. He just collects them for decorations and just for target practicing (like on cans and rocks). Which I have no problem with, since it's no different than taking a sword or nunchaku, and just freely practicing with them in the backyard or shit like that.
Other than that, I don't carry any respect for those who just use guns for the sake of killing others because it's just "fun", or killing some animal because they want a nice new rug or headpiece for their naked wall. I have to say the same for those who even use them for self-defense. If you knew how to properly move & defend yourself, you wouldn't ever need one in the first place.
Learn how to fight and defend yourself, carrying a gun doesn't make you any stronger than you were before.
