More on the Dangers of a Constitutional Convention

I've copied below an excerpt from an article by Tom DeWeese on the dangers of a modern Constitutional Convention. A gentleman took issue with my earlier blog post including an ad hominem attack that accused me of dishonesty (and stupidity). What he didn't mention is that the first Constitutional Convention in Philadelphia did exactly what the nay-sayers like me warn. The delegates threw out the Articles of Confederation and ignored the restrictions placed on their body by the individual states they represented. They went back to the drawing board and came up with a brand new Constitution that governs us today. In view of the historical reality, what possible evidence is there that the delegates to a new convention could not imitate their forebears?

We also are not the country we were in 1787 when the Constitution was written and 1789 when it was finally ratified. Can anyone doubt that in our abortion/gay marriage culture the rights of free speech for Christians, the right to bear arms, the right to free assembly, freedom from unreasonable search and seizure, etc. will be protected? And with so many liberal blue states can we be sure the state legislatures won't ratify whatever comes forth?
