> Just look at the constitution of the CSA

Actually, the Confederate constitution was even more hostile on the subject of states' rights than was the US Constitution.

  (4) No bill of attainder, ex post facto law, or law denying or impairing
      the right of property in negro slaves shall be passed.

So if say Mississippi were to suddenly see the light, they couldn't as a state pass a bill impairing the right of property in negro slaves.
