You’ve yet to show how the bulk of these tariffs were paid by Southerners. How did 30% of the population buy 80% of the imports?
To recap:
The reason for secession was the South’s desire to preserve slavery.
The trigger for secession was the election of Abraham Lincoln, which fed fear of the abolitionist foundation of the Republican Party.
The American Civil War began when units of the South Carolina Militia fired upon a Union fort in Charleston harbor.
You are mistaken. I have shown it many times. I will show it to you again.
How did 30% of the population buy 80% of the imports?
Well they didn't prior to secession. New York had rigged the game to get most of their money away from them. They would have done after secession because New York would not longer be able to keep the rigged game going short of invasion and conquest of the states that had seceded.
Oh, wait...
