Protected industries can export particularly when the tariff is combined with subsidies which was often the case in the 1800s.
You have never seen me defend tariffs from an economic perspective. They are mostly political instruments.
Compared to the North which is the issue the South was obviously economically backward, See Rhett Butler for details.
Wrong. The export figures for the united states in that era contradict you. Almost 60% of exports in 1860 were in southern cotton. Another 15% came from southern tobacco and southern rice. All else was relegated to the remaining 25%, and most of that was in agricultural grains that were not protected.

You demonstrably do not understand either, thus it is inconsequential as to what sort of an instrument you defend them for.
