This is a trick question but I hope it is one that will serve to demonstrate the reasoning behind my beliefs.
What is the purpose of the Constitution of the United States of America as defined by the founding fathers?
A) A way to mock the English and force them to see the folly of not allowing the US to have its independence without any need for violence or bloodshed.
B) A document which should be considered as "breathing" and "living" and subject to interpretation from any and all government officials who know so much more than we the people.
C) A list of rights guaranteed to the people of the United States of America.
D) An instrument which should be disregarded by politicians of future generations so that they may progress towards a more formal and distinguished form of global government or even evolve into a democracy.
E) A worthless piece of paper for politicians and citizens alike to blow their noses on and wipe their Aaaaa ..... aaaaaaaaa ... ACHOO! (Gesundheit ... to your health even)
F) A carefully thought out and planned document written in such a manner that it effectively restrained the rights and in many instances actively impeded and prevented the federal government from being the center of control and allocated powers of control and regulations to state governments in order to prevent a federalization of power.
And the answer is ... I bet you got it wrong!
Most people are probably going to answer "C" which is in a very limited extent and with a little bit of twisting and interpretation, considered and commonly viewed to be correct ... but it is NOT!
Looking at the state of political affairs in the playgrounds around the Beltway, many foreigners and even a good portion of Americans would be almost correct in answering "E" except that the question was what it was intended to be by the founding fathers.
Some of the more progressive people may very well believe that the answer is either "B" or "D" and given the current way of thinking, that would be reasonable to assume but still, the original question was in regards to what the founding fathers wrote about and what they proclaimed it to be.
The correct answer is actually "F" The Constitution was written specifically to limit any federal government.
"The Constitution is not an instrument for the government to restrain the people, it is an instrument for the people to restrain the government."
-- Patrick Henry
... when all government...in little as in great things, shall be drawn to Washington as the centre of all power, it will render powerless the checks provided of one government on another and will become as venal and oppressive as the government from which we separated."
-- Thomas Jefferson, 1821
