And that requires 2/3s vote in Congress plus 38 states. Not happening. It's not a rhetorical tactic when states and cities have actually confiscated guns before. Japan has around 20,000 suicides a year and less than half our population. Which is the problem here.
Broadly speaking the US, Canada, UK, and Australia, have probably the closest cultures of any four countries in the world. The only real difference is that Australia and the UK have weak gun culture while the US and Canada have stronger ones, big enough to influence politics. Japan has basically no guns and an extremely high suicide rate. Nobody is saying there should be no gun laws. That was actually based off a quote from a supreme court justice. But nice try. But what's reasonable? To a fascist, banning all speech critical of the government is 'reasonable'.
You can't use guns for self-defense in the UK. You wouldn't be able to buy that gun for the purpose of self-defense because self-defense is not a thing there. I can understand that. Handguns are useless against bears. So are shotguns. The Constitution does not grant rights - it recognizes them. That's why we have the 9th and 10th amendments. Constitution 101.
That leaves Australia, Canada, and the UK. Pu We are different. Unlike them, we have a codified constitutional guaranteeing individual liberties. This prevents things like hate speech laws and gun control - in other words, the rather nasty, authoritarian side of liberalism - for taking root. Maybe Obama should have thought of that before Fast and Furious. 60% of those from suicides. Would you resist if government tried to limit your right to speak freely?
Not something I care about any more than the fact the founding fathers wore wigs or the Romans drank wine laced with lead. You seem to think anyone other than other atheists care about sheep herding. You are mistaken.
