Can I ask why?
I'm not a US citizen either, and I find it a little weird how easy access to guns seems to be there. I think that other countries seem to have better controls while still retaining some access to firearms for legitimate purposes.
I genuinely don't understand the US outlook on this and I would like to.
For over 400 years, our ancestors lived with near constant danger and there were basically no cops or soldiers near enough to assist them. They fought the French, The Brits, the Spanish, the Mexicans, the Indians, the occasional slave revolt, and defended themselves from the usual collection of psychos, murderers, rapists, burglars, and thieves. Their firearms defended them against bears and mountain lions and those firearms fed their families.
My own father recalls when there was only one peace officer for his entire county (and he lived in a state that was one of the original 13 colonies).
Our friends throughout most of Europe can't recall NEEDING firearms for survival. They could trot over to the baker for a loaf of bread, trot over to the butcher for some meat. Their neighbors (and the law) were much closer. In America, your neighbor might be miles away and even today, the police might be an hour away. We relied on firearms out of necessity and they became part of our culture.
Americans are the descendants of people who didn't play well with others. They were kicked out of most decent countries and came here usually because they had no other options or because they wanted to be left alone. We aren't naturally inclined to call the police or take our problems to court. For generations there really was no law and no court for much of the country. Look at the way we grew. First, people moved into wilderness areas and civilized those areas. After considerable time, something resembling government moved in behind them. That was the case in most of our states. I will give exception to Hawaii and Florida because some form of law was already in place in both areas when Americans acquired those lands.
England sent settlers over here specifically with the expectation that they be citizen soldiers, ready to till the land or fill it with dead bodies as circumstances might direct. In America, if you weren't armed, you were dead. You either starved to death or you were at the mercy of any two or four legged predator. Our forebears were poor, but every home had a Bible and at least one firearm and both received considerable use.
