Max, what restrictions do you think are in the 2nd amendment? Are there any at all?
None. The Constitution limits government, not citizens. The Second Amendment doesn't give us our right of self-defense anymore than the First Amendment gives us our right of free speech or freedom of the press. It limits what government can do to stop us. There was a huge argument at the time of its writing over the issue exactly because of concern that some would think it limits citizen rights, not government.
What is the purpose of government? It's in both the Declaration of Independence and the Constitution plus quantly summed up in a quote attributed to Justice Oliver Wendell Holmes: "Your right to throw a punch stops where my nose begins".
Aside from national security and foreign relations, government also resolves disputes between citizens. While I may think I have a right to build a nuke in my basement, my neighbors may disagree. Same goes for shooting off a howitzer in my back yard or setting up landmines in my yard. OTOH, my owning an AK is a common form of self-defense. I can agree on mass weapons like the nuke thing, the howitzer thing and even the Claymore thing, but now when they want to take an individual weapon, that's there the line should be drawn.
