I'm from Germany. Guns are frowned upon, so what i did is frown. How could one so lightheartedly decide to purchase a weapon for self-/homedefense? You sir just made me question my view. In my country you wouldn't need a gun, because you are not to kill someone. And that's exactly what possession of a gun for said reasons mean: I am ok with killing a human. The moment where it's allowed to use one, the opinion hardens, resulting in a higher propensity to violence. Now murder is an option for both parties. So either you decide to play along, for the sake of I-shoot-you-first or you try to limit the spread of said thoughtprocess. And btw. If your SO doesn't like the thought of a weapon it might leave her more afraid then before, I know you'r already looking into advanced home security but also consider selfdefence classes because a weapon is not the way you should feel empowerment from a poor situation. And of course I'm sorry you had to experience threat to a loved one. hope you too won't find yourself haunted by this incident
"Opposing party" was just me trying to be fancy. "The other guy" would have done just fine ;) What I was trying to say is: Not having and not wanting a gun is just fine, until someone who does have a gun wants to hurt you. I've known crazy people with guns - yes, in Germany.
