Ummm, the vast, vast majority of the guns in the U.S. are used for legal, positive reasons like target shooting or self-defense. The number of murders per gun-year is incredibly low, effectively infinitesimal.
60ish percent of deaths by firearms are suicide. Owning a firearm is a risk factor for suicide. This is because many (most?) suicides are not carefully planned out and given considerable deliberation but are somewhat impulsive. Removing an easy means to commit suicide actually reduces suicide.
I'm neither pro or anti gun.
Ultimately, though, I do agree that these numbers are all negligible: there are more car deaths annually than there have been civilian gun deaths in the last ten years. The argument that is important to me is that gun rights simply aren't very relevant any more, and they are being used as a talking point for political forces who are causing a lot of harm to much more relevant rights.
