Agree.
We need Reps in Congress that will craft specific amendments to get to the States for a vote.
I am (currently) against a Constitutional Convention being called as (for me) it will lead to a Liberal takeover and quicker destruction of the country.
We can also see this in how many states have been increasingly receptive to having “shall issue” concealed carry laws. A state that would pass “shall issue” will not turn around and ratify a destruction of the RKBA.
So, we have two checks with the Convention: what it would vote to pass on to the states and what the states would ratify with a sufficient super-majority.
In any case, I think it is productive to discuss what changes would be made. That process has been begun by Prof. Randy Barnett's Federalism Amendment. See: www.federalismamendment.com
