Well you are correct about one thing, the flaw is not in our Constitution. The flaw is in the corruption of our people. That corruption is reflected in our elected officials. Our present Constitution cannot deal with the situation precisely because it was not written to deal with an immoral and unjust people. Consequently it must be strengthened to do so. There are three paths available as I see it. A convention of states (CoS) reduces the power of the federal government while increasing the power of the states thereby restoring freedom and balance to the country. Or we can continue to let what are essentially criminals lead us down the path to slavery. Or we will resolve the situation through armed conflict with each other. I choose the convention of states as the best present path. One that poses no risk as all the CoS can do is propose amendments which the states must ratify. Just like an amendment proposed by congress. Thus I believe there is little risk of a run away convention. And arguments that so state are simply incorrect. With due respect.
If we were dealing with decent people, I would agree with you. Unfortunately, we are facing Communists, Socialists, and liberals. They will not put a deadline on the ratification process. They will choose weasel words and ambiguous phrases that normal people will misread at first glance but that can be read differently at their convenience, once ratified. I don't believe a CoS will solve the problem. It's down to two options that I can see, and I am hoping we will discover an acceptable option that limits the power of government over us but avoids a second civil war.
