> Constitutional Convention is the abort button. It means giving a group of people basically limitless power to amend our Constitution

No, it doesn’t.

It gives a group of people basically limitless power to propose Amendments to the Constitution.

Any Amendments so proposed still require 3/4 of states to ratify them, either by votes of their legislature or by ratification conventions called in the states (at the option of Congress when calling the Convention at the request of states.)

Unless by "group of people" you mean not just the people in the national convention, but the people in the state legislatures or conventions, as well. But, at that point, you might as well say that by including an amendment process, the Constitution itself “gives a group of people basically limitless power to amend our Constitution”.
