Yeah. As an American these arguments are really absurd though. When was the last time a lone hero with a gun stopped gun violence? I think those arguments are really just the gun companies trying to market this idea of the "lone individual" as a hero protecting their personal space. It helps them sell more guns. But when the rubber meets the road, a "good guy" packing is more likely to shoot a bystander than an assailant.
The marketing seemingly appeals to men on the same grounds as video games -- there's some great protagonist who saves everyone with their powerful and timely shooting.
