[Non-Sequitur]

The real reason for the Civil War/War between the States was export taxs and not salvery.

There was no export tax. Duties or taxes on exports are unconstitutional.

By the way, there were two NORTHERN Slave States before, during and after the Civil War/War between the States

By the way, there were four NORTHERN slave states. Five when West Virginia was admitted.

[Paul C. Jesup]

"There was no export tax. Duties or taxes on exports are unconstitutional"

Where did you read this at? Originally in the Constitution, Import and Export taxs were the main taxes for the U.S.
