Yeah - any time someone presents an absolute in a debate about gun control, they've probably gone very wrong. America is just too damn big for any one narrative to be universal, and I say that in full awareness that it applies to my example also; the bulk of gun ownership isn't about that story.
My objection, then, is that I have approximately zero faith in the people making these rules to recognize that. If a gun law is written, it will with near-perfect reliability be written by people who know little or nothing about guns, designed for comfortably suburban settings, and passed out of fear of urban violence.
So... I don't know that we disagree so much. I can support more gun regulation in theory, but almost always oppose it in practice because the things that get written are high-impact on practical use, yet totally ineffective at their goals.
And there is a hell of a lot of difference between living in the (very) rural countryside, and living in a city.
I fully admit that my perspective is influenced by living in small country with relatively short distances between towns and cities (hell, it's even impossible to get more than 50km from the sea, anywhere in the entire country). But I honestly still think my reasoning stands up.
