Revising history to make a point not only doesn't make the OP right, it makes him flat out wrong.
And you guys are right - I just don't get it.
Canadians have quite a few guns, but they are mostly for hunters. All of the friends I know who hunt do so with bolt-action rifles, and almost never keep them in their homes. The ones that do keep them in the basement, locked in a trunk, with no thought to ever making them accessible in case a burglar came in.
There is no culture or need here to have weapons for home defense, because it generally isn't an issue.
The guys who wrote the constitution were pretty amazing and got a lot of things right. The proof is in the pudding and America is a great nation because of it. They weren't perfect however, and were still humans who made mistakes. I think the 2nd is not an outright mistake, but something that wouldn't have been written as it was if they had the ability to see what the future held.
But you guys have it mostly right, 99% of gun owners are mostly responsible, and being able to defend yourself in your own home is a good thing. I just think that countries like Japan, with strict gun laws and extremely low gun crime rates have done it better.
The biggest difference between the US and Japan and most other counties with strict gun laws is that we have always had a much higher rate of violence and gun ownership. We have more guns here than Japan or Australia has people. Assuming we adopted a policy similar to Japan, how many years would it take to get over 200 million guns off the streets? Law abiding citizens might hand their's over, but they will continue to be easily accessible on the black market for decades. That leaves armed criminals free to do as they wished with minimal risk from their victims. We'd be sacrificing the ability of our citizens to protect themselves (violence of all kinds is much higher here than in Japan) for an idea that would take at least half a century just to see if it even worked. Maybe it was the right choice for Japan, but it isn't for us.
