Unsurprised, I note that you chose not to argue with the fact that the 14th Amendment conferred jurisdiction on the central government to protect innocent human life from state government depredations and, in the Equal Protection Clause thereof, specifically requires Equal Protection of state and local law for each "person" under any given state's jurisdiction.
Besides there being nothing before the 20th century to justify your position here's some homework reading for you eh? The 14th Amendment was not meant to destroy the states, yet liberals, 'conservatives', and Progressives have done just that with it. All under different auspices, all for different reasons, but usually accompanied by silly catchphrases such as 'for the children', 'protecting the family', etc.
Suffice it to say that the view of the 14th Amendment advocated by the site you linked could as easily have been advocated by the "legal department" of the KKK.
When accessing that linked site, one can easily smell the aroma of nut fudge cooking up through the cracks in the skull of the site's author.
