I don’t know why so many people believe the founding fathers would think differently if they saw the world of weapons today. They had just fought and won a war largely due to the ability of commoners to fight off the threat of the most powerful colonial power in the world. The second amendment was written to allow people to defend themselves collectively (hence the mention of militia) from the threat of nation states and corrupted powers, not carjackers and armed robbers. If they saw the world of weaponry today, I wouldn’t be surprised if they would interpret the second amendment to include grenade launchers and machine guns...because that is what the potential external threats (and possibly internal threats) have become. You may believe the world has changed, but I still find it short sighted to go around disarming people. The count of people killed in genocides even in the last half of the 20th century is enough to dissuade me from putting my security solely in the hands of a government. And I say that as someone who generally hates America’s obsessive gun culture.
