I agree to an extent, for the reason you stated.
On the other hand, the Constitution has already been foolishly changed, the 16th and ill-conceived 17th Amendments for example. Patriots need to elect a new patriot Congress in 2020 elections that will promise to propose a repeal amendment for those amendments to the states for ratification.
You do not need to repeal Amendments that can simply be nullified.
If we’re going to change the Constitution to save the Republic we’ll need to begin with repeal of the 19th.
