That point has been well refuted, - in the 'squalid' thread for one. The principles of the 14th are being misinterpreted, thus 'used', sure, just as the whole constitution is being used by socialists of both parties.
But the constitution itself, and the 14th, cannot be faulted as 'destroying' anything.
This is hype, by the socialist statists themselves. They wish to discredit the words of the constitution. -- One recently claimed that the 14th is written in some sort of 'code'.
It is written in plain english, and simply says that states cannot write laws that abridge/deprive any person of life, liberty, or property, wihout due process.
The idea that this language somehow 'centralizes power' is looney.
