The 14th Amendment was what opened that door by offering corporations "equal protection" to people.
We refuse to identify the enemy(progressives) so we are simply falling to the Sun Tzu principle.
If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer a defeat. If you know neither the enemy nor yourself, you will succumb in every battle - Sun Tzu (Art of War, Chapter 3)
Nobody, nobody wants to name progressivism. And the Founders are unpopular. So we succumb in every battle.
