I agree with Clint's argument.
For me, no civilised society should have dangerous weapons. I had a chuckle a while ago reading a YouTube comment (says it all, doesn't it?) where someone had tried to insult the UK using some teenagers who had gotten into a "knife fight" in his argument. A UK resident lovingly retorted that if it were a gunfight (*cough* USA *cough*), none of those teenagers would still be alive and they would probably have taken a school down with them.
You can use the self-defence argument for gun-ownership all you like, the reality is that you don't need a gun to defend yourself in most situations; guns are often stolen from people who bought guns for "self-defence" and are then used in crimes--further fuelling the problem and, most importantly, the fact that guns don't serve any other purpose than to be a dangerous weapon.
And yet, so often, digging deeper into the minds of the pro-gun whackjobs, you'll find that they take pleasure in hunting (this already sends warning signals) and they believe quite firmly that their governments are trying to take their guns away so that they become slaves to the military or some such nonsense (again, hello, these are people you want owning dangerous weapons?)
There's also the liberal argument: in a liberal society we should be allowed to own whatever the hell we like. And yes, I'd agree with that, but not if it poses a risk to those around you. This is why we have so many fantastic laws that prohibit danger to others: you need a licence (proof that you are able) to drive a car, you can't be drunk when you drive, you can't kill each other, etc.
I like to think that (most) laws are there to protect us from the whackjobs out there and, when they fail at that, to bring justice to them.
Nobody has a good reason to own a gun.
And those who think that they do are usually knuckle-draggers with tiny dicks who think that when three guys with guns breaks into their house, they can act macho and manly and shoot the bastards dead and be a hero. It's just such a shame how infrequently that actually happens and how often situations like that escalate to the point where they and their families get slaughtered.
I'm reminded of Rowan Atkinson in The Thin Blue Line:
D.I. Grim: "You're supposed to ask questions to find out who's a suitable person to own a gun."
Inspector Fowler: "That's right. And surely the first question must be, 'does that person wish to own a gun?'."
D.I. Grim: "Well of course."
Inspector Fowler: "And if the answer to that is 'yes', then clearly that person is not a suitable person to have one."
The only members of a civilised society who should be permitted to wield firearms are military and police.
And even then, police is questionable, especially in South Africa where a fair number of firearms are stolen FROM the police. In which case I'd argue that only special task forces should be permitted to hold firearms kept for evidence (until they can be destroyed) and use firearms in the line of service.
All the same, it's sad that discussions like this even need to happen--shows how far we all still need to go before we can ever consider ourselves or where we live "civilised."
