You are going to try to shift the discussion to the merits of protectionism? I don't think I will bother to follow you down this path of misdirection.

By referring to Trump, I am suggesting that protectionist legislation does not on its face suggest a scheme to benefit one region of the country to the detriment of another. You have failed to show how the tariffs of the 19th century did that. The Southern states were free to build or purchase their own ships. They were free to sell directly to foreign buyers if they wished. How did the North’s three card monty work?
In coming days I will post further information demolishing your bogus arguments.
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.
