It is relevant. You're probably not going to need your fire extinguisher to deal with "that guy" who's pulled out his fire extinguisher in a confrontation. It's kinda hard to carry under your jacket.
The fundamental difference between American and "non-American" (for lack of a better term) views on gun ownership and rights is the individual vs collective rights. Americans generally value individual liberies (freedom to), while "non-Americans" value collective liberties (freedom from). This viewpoint applies to many American vs non-American discussions (firearms, education, healthcare, etc), not to go too far OT.
Like Original Earl has said, I have never felt a fear for my life here in Canada. Only once have I ever felt uneasy walking through downtown Vancouver (including the bad parts of the Downtown East Side - the druggie area of town), and I only know of one person who's ever been mugged. Our present situation north of the border means that there's little reason
to to carry a gun. The threat of personal harm simply doesn't exist to the same level as it does (or you perceive it to) south of the border. This obviously varies from location to location, but in general, there's simply less crime here. For me, the potential for irresponsible gun owners is too high to allow everyone access to firearms. Yes, this is going to sound like the bleeding heart argument, but think of all the accidental injuries and deaths related to firearms in the US. Those are all the irresponsible people who still have the same rights as some of you, the responsible gun owners, and IMO are abusing those rights.
I'm writing this from a background of having firearms in the house. I have my firearms certification and hunters card. I've shot plenty of wildlife, and with a bit of paperwork, I could easily have my PAL (Possession and Acquisition License - necessary for owning firearms and purchasing ammunition). I understand that there are recreational uses for firearms, and I'll fully support those, but in my opinion, needing a gun because others
might have one is a sad situation to be in. I'm not saying that the answer is simply removing the guns (because that's just not going to fly), but instead remove the
need to have one in the first place. Again, I'll go back to my original point - I haven't ever felt fear for my life here in Vancouver, even in the "scary" parts of town.
