Well, that's because you see the Constitution as starting with the Second Amendment and ending with the Second Amendment. This is why you ignore the fact that the rest of the Constitution is not the same document it was in 1785. You see, we are not Islamists who demand that an original source document be preserved in brittle concrete while ignoring the passage of time.
And, no Turtle. The Founding Fathers had tyrannical government, the necessity to hunt, and local security against natives in mind. There is no need to speculate about the Founding Fathers and why they issued the Second Amendment. Given the centuries long relationship between Lords and peons, the context of the historical era, and the words expressed by the Founding Fathers themselves, we all know why they issued the Second Amendment. And we can also all agree that handing out weapons freely so that nutcases can roll up on late-eighteenth century schools and corn festivals wasn't it. The Founding Fathers would be ashamed of what you people have done with the Right. Despite clearly believing in an educated political elite that would at once serve the people and enlighten them, they trusted you all to be responsible with these Rights. Of course, the very notion of a person lining up school children or senselessly murdering masses for the sheer glory of it wasn't as fashionable then as it is in our era, where we have grown quite accustomed. You are failing the Founding Fathers because you are willing to sacrifice the integrity of the nation and the well being of its children over a selfish need to define your liberty through multiple metal objects.
And isn't it funny how you people can declare that a "gun is just an object" and not the problem, yet the object of a gun appears to be the only thing that defines you as a person? When it comes to gun violence, the gun isn't the problem, but when it comes to your notion of liberty, the gun is everything. Not a lot of rationality here. But hey, let's keep this game up until Remington or another joins Colt. And on and on and on...
