Well I could see if someone were a danger to society or something of the sort, then I could view it as wrong. Let me assure you that all the weapons in my house are all legal. I use guns for sporting purposes only, well unless someone tries to rob my house, or cause harm to loved ones.
So I dont feel its wrong at all, guns are very interesting pieces of machinery. As long as you have respect for the weapons and you look at them as tools instead of toys I dont see the problem.
Your view?
