An article V convention is the only peaceful solution other than secession and forming a new Republic.
An article V convention IS secession and forming a new Republic. No amount of safegaurds can possibly prevent this. Regardless of charters and promises conventioneers will have absolute authority to completely rewrite the Constitution. Do you honestly believe Marxists will not be in charge of this process?
Invoking Article V is extremely dangerous for the cause of liberty. I wouldn’t trust that progressives would be prevented from taking over a Constitutional Convention.
