The French Enlightenment and the Revolution that followed corrupted the gifts of the English/Scottish Enlightenment and the related American Experiment that followed.
From the time of Athens, all sensible framers and the founders knew that Democracy in its direct form was death even when led by a Pericles.
Conservatives know that preserving our heritage and the forms of value within our culture need change as time passes. But that change is careful and prudent -- Reform as opposed to Revolution.
Perhaps there will come a day where the large majority of our republic understand and value what they have inherited and I would then join such a crafting begun annew. But, with American Idol having such a long season, I don't expect that day too soon.
I'm not espousing a wholesale tampering. Nor am I espousing crafting a new constitution.
A Convention for Proposing Amendments is merely a way for the states to gather in convention and propose an amendment on a subject predefined in their petitioning language. There would only be wholesale tampering if two-thirds of the states requested a general revision of the Constitution in which any amendment on any subject could be introduced. No one has seriously suggested that in over 200 years.
However, any day that Congress is in session, it can propose any amendment on any topic, to include so many amendments that it would constitute a general revision of the Constitution. Note that something like that hasn't happened since the 13th, 14th and 15th Amendments were introduced in the days immediately following the Civil War.
If you're in fear of a "runaway" convention, Congress has created safeguards to prevent that.
