DiogenesLamp: "Yes, the confederate constitution made it very clear, and I presume they did this because they were fed up with people pretending the US constitution wasn't also clear."

The US Constitution there refers to more than just slaves.
The Confederate Constitution refers specifically & only to African slaves.

It's a distinction Confederates went out of their way to make clear.

You are trying to get the indentured servants "Tail" to wag the Slavery "Dog."

The constitution was specifically referring to slavery. There is no need to tell states to respect criminal convictions (prisoners) or contract law (indentured servants) of other states.
