Well, since you asked…
Firstly, I think a lot of people on both sides of the debate in the US would do well to remember Most first-world countries allow civilian ownership of firearms.
America is not The Only Country In The World Where People Can Own A Gun. It is entirely possible for the average person, should they be so inclined, to legally obtain firearms in the UK, Australia, New Zealand, Canada, South Africa and many (most?) Western European countries.
What is true is that most of those countries restrict ownership of Military Style Semi-Automatic Rifles (MSSARs). There’s been, very approximately, eleventy gazillion posts here from people saying banning MSSARs because of how they look is stupid and look at all these civilian hunting rifles that will also be banned.
Here’s the thing: MSSARs tend to attract a certain type of person. Not you, [del]naan bread[/del] Perfectly Sensible And Reasonable SDMB Poster Who Legally Owns a Semi-Automatic Rifle (see my signature), but you know perfectly well the sort of people I’m talking about. The sort of people who give you, the sensible gun owner, a bad name by wearing full camo and tactical rig to the range (despite not being in the military), openly talking about how people of the “wrong” ethnicity/religion/minority group should “fuck off back to where they came from” (possibly with the suggestion guns like the one the speaker has may be employed to expedite this process), and people who clearly have “issues”. These people are not queuing up to buy bolt or lever-action hunting rifles on principle.
Do I think MSSARs should be banned? No.
But for some reason, MSSARs seem to be the weapon of choice for unbalanced individuals looking to cause mayhem. When was the last time someone went on a rampage with a Winchester lever-action rifle? I suspect the photographs accompanying news reports of such an incident would all be in sepia and have a lot of stern people with moustaches in them. Thus, I understand where the “Ban Assault Weapons” people are coming from, even though I don’t necessarily agree with them.
Personally, I think the idea of owning guns to Defend Against Tyranny™ is laughably absurd. Using guns to fight “The Government” or whatever stopped being even moderately realistic before World War II. Every Belgian (and French, for that matter) farmer had a shotgun and that did approximately fuck all against German Panzers and Stukas. In the modern era with all the stuff the military has access to? Someone (or even a small group of someones) has no chance.
Now, here’s the thing - I believe it’s staggeringly unlikely the US will “Ban Guns” full stop, for the simple reason there’s too many of them and there are numerous court decisions on the subject, including one which I believe asserts the right to own handguns for self-defence. Combine that with the acceptance of “hunting” or “sporting” arms and I think most sensible people agree the black helicopters won’t be coming for anyone’s Smith & Wesson Model 10, their Remington M870, or their Weatherby Mk V anytime in the foreseable (or even distant) future.
I do, however, think it’s possible in the US that MSSARs will eventually either end up like full-auto weapons there are now (New manufacture prohibited, existing guns must be registered, ownership requires police checks and payment of a tax).
And as someone mentioned in another thread recently, the vast majority of gun owners in the US would probably hand their guns over if they were banned for the simple reason those people value their general existence, family, jobs etc - not to mention being alive and/or not being in prison - far more than they value owning a TactiCool MSSAR.
I guess the point I’m making is that banning MSSARs would not, IMHO, be The End of Liberty In America or anything like that. It hasn’t been anywhere else civilised in modern times.
Having said all that, though, I don’t think the guns are the issue. I think the US has some very serious social problems (Honestly, how the fuck can any reasonable person possibly have a genuine objection to universal health care???) and rather than getting worked up over things like whether a semi-auto AK-47 is a greater public safety risk than a Ruger Mini-14, the underlying causes - why are people going on shooting rampages? - need to be addressed, and the money that would be spent implementing and enforcing an MSSAR ban/restriction would be better used going towards social services, mental health and education etc.
