Used in warfare
That's for military. Used in every country in the world and subject to specific laws.
hunting
That's for hunters. Used in every country in the world and subject to specific laws.
sports
That's for sportsmen. Used in every country in the world and subject to specific laws.
However, not every country gives free access to lethal firearms to the general population (and they are right not to do so!). Because, unlike in case of most military personel, hunters and sportsmen, the general population consists in much larger measure of psychopaths, violent maniacs and retards. Giving such people free access to guns produces school shootings and murdering people while they give public speeches.
And my argument still stands: you can't compare cars to guns, as the former are not designed specifically to kill, the latter very much are.
you have surrendered to the «terror of guns»
What? I own hunting guns myself. But I had to meet certain conditions to obtain them and I'm mentally healthy and stable enough to have them. I certainly wouldn't want everyone I see in the streets everyday to have access to such weapons.
