Obama angry after Oregon shootingChilling warning on 4chan Shooter kills at least 10 at college294 mass shootings in 274 daysHow guns have shaped AmericansGuns deaths vs terrorism deaths in two charts
In his very fine speech this morning, full of sorrow and frustration, President Obama made a mistake: Australia is not like the United States. We decided not to be.
We decided to grow up instead and become a more reasonable, rational society that explicitly values human life and prefers to think the best of people, rather than the worst. 
The US is too immature a society to be allowed to play with guns. It has never shed its Wild West mythology. Americans still use their courts to kill people, which sends a message in its own way. Read The New Yorker's account of the Rodricus Crawford case and see a state that thinks taking a life is a no big deal. It's a country that values property more than life.
Unlike the US, we collectively decided to have a decent social safety net, the concept of a living wage and make good education freely available. Most of us are wary of those with extreme views of any kind. Inherent scepticism about church and state turns out to be not such a bad thing.
Unlike Australia, the US is at war with itself, strongly divided on racial, religious, political and social lines. We have our problems, significantly worse in some places than others, but overall our gaps are bridgeable. The US seems to prefer to use its societal chasms as moats and defend their borders.

Dystopian view
The dystopian viewpoint is a significant theme in American literature, the assumption that the country is a disaster away from rape and pillage, from turning into plundering carnivores. Having never made peace with its past, which pretty much was one of rape and pillage, it hasn't escaped it.
From The Road to Hunger Games, the effect is numbing. The National Geographic Channel features a show called Doomsday Preppers, a how-to guide for armed and dangerous "survivalists" building redoubts on the assumption that everyone else is armed and dangerous and out to get them. It is a nation that is collectively paranoid.
It doesn't seem to help to have a large body of religious fanaticism - it doesn't help anywhere, whatever the particular brand of religion. There's little difference between the violently fundamentalist Christian, Muslim, Hindu or Jew.
There's an American brand that hasn't evolved far from justifying slavery. It carries a fundamentalist certainty that is in equal parts both ignorant and frightening. The concept of American exceptionalism - that God has a chosen mission for the USA - is a dangerous adjunct.
It's all fodder for the deranged fanatics of the American gun lobby, with a bible in one hand and an assault rifle in the other. It's fuel for the paranoid interpretation of a line in the constitution that is a blatant anachronism.
We have our share of deranged individuals, but we try not to empower them. We don't promote violence for good or bad and increasingly decry the bad.

Protection myth
That was another mistake Obama made: talking of responsible gun owners having firearms to "protect their families".  The statistics have long been in - having firearms is more likely to endanger families than to protect them. Obama is not immune to the paranoia.
And so, when domestic terror struck at Port Arthur and John Howard showed political leadership, we overcame our ratbags, our Leyonhjelms, and agreed to reasonable controls on firearms. They're not particularly tough, except in restricting access to weapons specifically designed for killing human beings. Only an NRA member could think that unreasonable.
The restrictions demonstrably work.
The immediate American-like response at the crazier end of the National Party has abated. It's safe to say we're now rather proud as a nation of our gun laws. We haven't suffered another mass shooting. In National Party heartland, there are men alive who would not be if guns had remained so freely available when they were troubled youths.
And I write as a person who grew up with a knowledge and enjoyment of and respect for firearms. My father was a policeman. We had firearms in the house. I have a gun licence. It's been a little while now, but I enjoy shooting clays when I have the chance. And I think only a madman would want to water down our gun laws or, in America's case, not adopt them.
But, no, we are not like America. We're a society the USA should aspire to be.
