That argument does not stand upon examination. While seemingly impressive the documentation does not support the argument that the amendment was not consitutionally adopted.
The clownish Johnson's attempt to allow the slavers to regain power before Lincoln's body was cold was rightly rejected by Congress which demanded new legislatures not filled by traitors. This resulted in millions being allowed to vote who had been suppressed by the Slaverocracy. Reconstruction could only take place after the suppression and removal from power of all traitors who had fought against the Constitution.

No legitimate legal authority maintains that this amendment or others whackjobs dispute were not legally adopted. Crackpot sites and organizations' opinions are irrelevent.

When the South attempted to destroy the Union it brought destruction upon itself. When the Slavers attempted through a campaign of Terror to reconstitute slavery in all but name Congress stepped to remove the Traitor-filled legislatures and allow ones to be elected which represented ALL their populations not just the slavers. Case dismissed.

Those same "Traitor-Filled" Legislators of the southern states voted to ratify the 13th amendment.

So either the 13th Amendment is Void, or the 14th is void. Take your pick, you can't have your cake and eat it too.
