The original was contradictory, it was the result of a political compromise. The current version is not - not legally anyway. Three new amendments to the constitution made the earlier contradictions about slavery a dead letter of no legal effect.

That is what amendments do - they change things, and those ones came at no small price. So what is the point about complaining about a problem that six hundred thousand people already lost their lives in a successful attempt to resolve? Slavery has been illegal in this country for a century and a half.
