Trying to drag slavery into the document distracts and waters down it's central focus, and that is why the other members of the committee struck all that anti-slavery language out of the document.
At the time, all 13 colonies were slave states, and i'm confident the document would never have been signed if that anti-slavery language had been left in it.
The civil authority behind the declaration were the States themselves, not Thomas Jefferson, who was only part of the Virginia delegation.
