Then I don't think you understand how a convention of states works. Any amendments proposed by the convention would still need to be ratified by 3/4 of the states. Unless you think there are 38 state legislatures that are prepared to repeal the Bill of Rights, I think your concerns are misplaced.
I think the greater concern is that we would have a difficult time getting ANY proposed amendments ratified. But I don't think that is an excuse to not try.
They aren’t even half way to gathering enough states to even call the convention, so any consideration of ratification is premature anyway.
I think the most likely positive outcome would be to pressure Congress to propose one or more of the more popular amendments before the convention was ever called.
But stranger things… 15 years ago, who would have guessed we would have constitutional carry in over 20 states?
“I think the greater concern is that we would have a difficult time getting ANY proposed amendments ratified. But I don’t think that is an excuse to not try.”
Which is why we should start very small. Propose 1 amendment: Term Limits. Leave everything else alone for now. Make the entire argument about that. Get it done, show the people it will work, then go back again for more. Nothing says we can only have 1. Start with an easy victory.
