Starkers, Jafo will ban me long before he bans you, don't worry so much.
It's not the difference in gun ownership that makes the murder rate in the US 4 times as high as it is in Australia. Switzerland has a massive gun ownership rate, with army service being mandatory, and every member keeping their weapons at home, yet they have an even lower murder rate than Oz does. When your gun ban was enacted in 1996, the only impact it had on the murder rate was a brief spike after it's implementation, no reduction seen. Other countries all get the same results with their gun bans, and repealed gun bans, dick for crime prevention from reducing gun availability.
The reason the US has a high rate, is because the US is fucked, ethnically, socially, and legally. We have a massive criminal gang element, that our judiciary refuses to prosecute on minor beefs, despite having the legal tools to do so, financially incentivised by our pointless prostitution, gun, and drug laws. We have a very large transient population composed primarily of the mentally ill, who were expelled from institutionalization because the courts ruled it was wrong to do so unless they were proven to be a danger before hand. We have an extremely ethnically diverse population, complete with the racial strife that comes with it. We also have most of our murders in places where people have been disarmed by the government. These areas also have the worst schools, particularly in those ethnically diverse areas, and our failing education system leads to poverty, which makes being a gang banger and killing your neighbors for money a lot more attractive than wasting time in school.
I am "armed to the teeth" because I have a loaded 45 for self defense, a loaded shotgun for that damned skunk that keeps crawling under the house, and a collection of rifles my grandfather made. It's not fear of my government, the fact that I have them is why I have to worry in the first place, antique hunting rifles aren't particularly useful for taking on the government anyway. That the tards would freak out at the idea of a guy with a few dozen guns and thousands of rounds of ammunition is simply their inability to grasp obvious things, like ammunition being radically cheaper in bulk, and responsibly carrying requiring a great deal of practice for those of us who aren't innately good shots that were simply born with perfect aim. My father was, he can hit what he's aiming at without practicing, ever. I have to put a hundred rounds in a target before I'm hitting it most of the time at 50 feet. To responsibly conceal carry, I will have to go through a few hundred rounds a year to stay in practice, and that costs two to three times as much if you buy your ammo twenty at a time, instead of a thousand at a time.
It's also not my fault if someone makes me kill them. It's theirs. If you attack someone else, and they kill you in self defense, it would be a tragedy if it bothered them. First they've been accosted by some animal, and now they're supposed to feel guilty about surviving the attack? They should be pissed at the inconvenience you've caused them while they're being harassed by the authorities. If anything, when someone without compunction or self control gets themselves removed from the living, it should be a joyous occasion, one less animal wearing human skin, preying upon the sheeple.
