How did the Constitution "allow" slavery?
Explain.
Prior to the Thirteenth Amendment, the United States Constitution did not expressly use the words slave or slavery but included several provisions about unfree persons. The Three-Fifths Compromise, Article I, Section 2, Clause 3 of the Constitution, allocated Congressional representation based "on the whole Number of free Persons" and "three fifths of all other Persons".
That is not an "allowance" for slavery. Especially not explicitly so.
However, that language does support my claim that blacks especially were not recognized as "persons." Three fifths is not a whole.
Now I'm confused.
In the same post you say:
The constitution says that ALL persons are entitled to the equal protections of our laws.
and:
However, that language does support my claim that blacks especially were not recognized as "persons."
Is the Constitution saying that not all human organisms are "persons" entitled to the equal protections of our laws or not?
Did I really need to put emphasis on the word THAT?
Clearly, there is a bit of a contradiction in the wording between those two parts of the Constitution. Especially if taken out of context.
However, you should already know that the amendments were added for clarification and to get the damn thong ratified. So, there should be no misunderstanding as to what the spirit and purpose of the language is.
