Firearms, generally, pose a public threat. In ANY civil society, when threats are present, we decide as a society where threats are acceptable given the benefit they pose to society. Currently, cars kill 30,000 people per year. Guns kill roughly the same. Yet cars are vital for almost the entire adult population when it comes to transportation, income production, health care, etc.
Guns, conversely, are important for almost nothing among the civilian population. Not food production, not income production (again, talking civilians here) and not even self-defense. The SCOTUS artificially carved out a personal defense measure in the Heller case, but even there Scalia admitted that not all restrictions would be unconstitutional, and not everyone, everywhere, is entitled to carry a gun.
This isn't "nonsense", this is the test the supreme court applies on a case by case basis when it balances state restrictions with citizens' rights. Like it or not.
Your language is extremely revealing. You say "we" as "gun owners" like you're a special class of the population. You are not. (And that includes me, as I am a gun owner, too). You're subject to curtail of your rights for innumerable reasons. That's called reality, kid.
