"Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction."
Therefore, the 13th Amendment to the United States Constitution is unconstitutional law because it allows slavery to exist under a narrow exception for those who have been "duly" convicted for a crime. As such, modern-day slavery, by way of criminal conviction, necessarily encourages discrimination and denies a convicted person "equal protection of the law" guaranteed by the 14th Amendment, i.e. right to vote, supplying proof that the U.S. Congress had clearly written the 13th Amendment to conflict with the intent and meaning of Article 4 of the 14th Amendment to the Constitution.
