When the Constitution of the United States was Created: on September 17, 1787, African -Americans was considered property of their slave masters and wasn't considered a citizen or whole human. Since  September 17, 1787, there have been 27 amendments to the constitution but little or no change to ensure that African- Americans born on this land is recognized as full citizen, given the rights of a full citizen, and able to enjoy and practice citizenship without the ugliness that harbor from citizens that do not acknowledge our citizenship rights. 

There is a few articles of Amendment that does not include African-Americans as a citizen but as mere laborers, 3/5 of a person, and for the purpose of determining representation in Congress.

                      THE CONSTITUTION of the UNITED STATES 

Article 1 Section 2:The House of Representatives shall be composed of Members chosen every second Year by the People of the several States, and the Electors in each State shall have the Qualifications requisite for Electors of the most numerous Branch of the State Legislature. No Person shall be a Representative who shall not have attained to the Age of twenty-five years, and been seven years a citizen of the United States, and who shall not,
when elected, be an Inhabitant of that State in which he shall be chosen.
[Representatives and direct Taxes shall be apportioned among the several States which may be included within this Union, according to their respective Numbers, which shall be determined by adding to the whole Number of
free Persons, including those bound to Service for a Term of Years, and excluding Indians not taxed, three-fifths of all other Persons.

David Gans is the director of the Human Rights, Civil Rights and Citizenship Program in which he stated that “someone who was enslaved would be counted as three-fifths of a person” for the purpose of determining representation in Congress.

Article IV  Section 2 :[No Person held to Service or Labour in one State, under the Laws thereof, escaping into another, shall, in Consequence of any Law or Regulation therein, be discharged from such Service or Labour, but shall be delivered up on Claim of the Party to whom such Service or Labour may be due.]*. This clause contemplated the existence of a positive unqualified right on the part of the owner of a slave that no state law could in any way regulate, control, or restrain. Consequently, the owner of a slave had the same right to seize and repossess him in another state, as the local laws of his own state conferred upon him, and a state law that penalized such seizure was held unconstitutional. Congress had the power and the duty, which is exercised by the Act of February 12, 1793, to carry into effect the rights given by this section, and the states had no concurrent power to legislate on the subject. However, a state statute providing a penalty for harboring a fugitive slave was held not to conflict with this clause because it did not affect the right or remedy either of the master or the slave; by it the state simply prescribed a rule of conduct for its own citizens in the exercise of its police power.

THE AMENDMENTS TO THE CONSTITUTION OF
THE UNITED STATES AS RATIFIED BY THE STATES 

Amendment XIII
Passed by Congress on January 31, 1865. Ratify ed December 6,
1865.
(Note: A portion of Article IV, Section 2 of the Constitution
was changed by the 13th Amendment.)
SECTION 1.
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. 

This supposes to be the 13th Amendment to the US Constitution: Abolition of Slavery but with the word except it regulates slavery. It only worded it differently so that the same meaning of Slavery is possible thru punishment for a crime that party has been convicted.

These small changes make an incredible difference in the Constitution and African-American. These small changes will produce a more productive American people .to hold the truth that We the People of the United States, in Order to form a more perfect Union, establish Justice, Insure Domestic
Tranquility, provide for the common defense, promote the general welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United State of America.

"The past is behind, learn from it.- If certain documents support and give power to the misuse and abuse of a Nation of people, from the past and have not corrected itself the past is never behind but always in the present  The future is ahead Amended to prepare for it,- The future is only ahead if the Constitution of America correct the wrong of the past to build a solid American where all men/women are truly equal. The present is here, live it."- The present must amend for the past, by removing subliminal words of the constitution to have a society of free people. Freedom is God's gift to all. No man or woman grants you freedom or takes it away.

“Anytime you beg another man to set you free, you’ll never be free! Freedom is something that you have to do for yourself …Malcolm X in 1964

I am hoping to have these remark removed along with other articles to ensure the past never happen again.. this can only happen with your signature and support to have Congress review this document and go forth. 

Here is the process:

Under Article V of the U.S. Constitution, the states have the power to apply to Congress to hold a convention for the purpose of proposing constitutional amendments. This power was meant to provide a fail-safe mechanism to control the federal government.
