Note: the author concludes:
The ratification story of the Fourteenth Amendment, which shows the irregular and likely unconstitutional process by which it has been declared part of our Constitution, demonstrates that a major cornerstone of constitutional law is placed on a shaky and uneasy foundation. Unfortunately, although one may wish to remedy the constitutional wrongs committed during its ratification, it is apparent that this cornerstone amendment should be left in place, lest the entire house of higher law as we know it should come toppling down. It is not too late, however, to shore up the foundation of constitutional jurisprudence. Congress and the states should repropose and ratify the Fourteenth Amendment, and thereby ensure the principles of equal protection and due process which the Amendment guarantees.

“The people of the South have rejected the constitutional amendment (14th), and therefore we will march upon them and force them to adopt it at the point of bayonet, and establish military power over them until they do adopt it.” Senator Doolittle, Wisconsin.
