That's the part that amuses. "Call a Constitutional Convention!". Can you imagine what sort of insanity would come out of that?
I just did... all the wackiness, political correctness, and socialist BS you find in documents like the UN "Rights of the Child" and the EU Constitution. Rather than defining and limiting the powers of the State, they would try to assign rights to people (by various grievance groups, of course) and end up leaving us with no rights at all.
