I am quite sure that you know th difference between importing slaves from AFRICA, and slaves from the US. Big difference. Since the US forbade African Imported slaves, then the others would be a "domestic" import of slaves.
(not African)
No, I don't believe I do. Imports are imports regardless of the foreign country they originate from. The confederacy considered the U.S. a foreign country. Their constitution specifically protected imports of slaves from that country. Are you now admitting that this is true?
