One of the absolute worst facets of American political debate is the hagiography of the founding fathers and their constitution. For instance, those idiot teabaggers, crying about how they want their constitution back and how the country should be like what the founders intended. Why? It's the worst, most intellectually vacant argument for or against policy. So much of the constitution is no longer relevant today, but politicians and other Americans still resist changing it because it's "what the founders wanted." It's maddening.
These people are not obsessed with the founding fathers like how a pale basement-dwelling teenager obsesses with Paris Hilton. They believe that the Founding Fathers created the ideal system of government, and believe that it should be kept according to their intent. It is not solely because it's "what the Founders wanted." To suggest that is to suggest that anyone who believes in pure Constitutional principals is of a lower plane of intelligence.
And as for the original post, nobody is obsessed with the Constitution. Some people just think that the Constitution sets out the ideal form of government, which should be kept that way.
Why aren't they obsessed in that way? You're not substantiating your arguments.
