Oh boy, another gun thread. I'd love to read through ten pages full of logical fallacies on both sides of the gun control debate, but I'm tired, so I'll just provide the bullets of my POV.
What I believe is that all people should have the right to self-defense, and therefore, on principle, not statistics, firearms should be legal and available. However, I believe that screening checks for purchasing firearms should be stricter and more thorough than they are at the moment. People should need licensing to own, and a separate one to carry. Furthermore, the weapons available to civilians should be limited within reason. High-capacity rifles and shotguns have no non-military need, and the same goes for submachine guns and automatic weapons. There is no need for them for self defense (a regular shotgun or pistol should be good enough), and for hunting you would rarely need more than a few rounds per mark, unless you're batshit insane and you're hunting bear or wolf (in which case, a better scope and a nice hiding place are more useful than a high-capacity rifle).
We should consider that violence comes not from the availability of weapons, but the culture. The US has a violent culture by itself, and banning guns would only cause militia groups to turn into terrorist cells. Also, Switzerland has an incredibly high gun-ownership rate, but its gun crime rate is extremely low. Crime and gun ownership are not correlated as much as some people think it is.
Consider the nations with the strictest gun control policies: Japan, the UK, and Australia. Notice a pattern? They're all island nations! They have control over smuggling much better than countries connected to continents. As such, criminals will have a harder time getting guns if there is a gun ban in those countries, which is one of the reasons gun control has worked there. Compare that to America, which is fortunate to have Mexico as its neighbor. With a drug war raging on, it's incredibly easy to get smuggled weapons into the US. Because of that, criminals in the US will always have guns until border smuggling ceases.
The last thing I want to say is that people shouldn't say things like "Americans are barbaric", because that's just uneducated. There are large factions in America that want gun control. Furthermore, we're not all rednecks who shoot people for stepping on our lawn; plenty of gun owners are responsible. It's just that you don't hear about the responsible ones because they don't shoot people for stupid reasons.
