How did the seceding states define their opponents: Answer, as "non slave" states.
I saw no purpose in making the board all but unusable with thirteen more posts on the same subject.
You quote Mississippi.. here is how the document begins:
" Our position is thoroughly identified with the institution of slavery-- the greatest material interest of the world.
Its labor supplies the product which constitutes by far the largest and most important portions of commerce of the earth. These products are peculiar to the climate verging on the tropical regions, and by an imperious law of nature, none but the black race can bear exposure to the tropical sun. These products have become necessities of the world, and a blow at slavery is a blow at commerce and civilization. That blow has been long aimed at the institution, and was at the point of reaching its consummation.
There was no choice left us but submission to the mandates of abolition, or a dissolution of the Union, whose principles had been subverted to work out our ruin. "
This isn't just somebody's random opinion, George. The delegates of Mississippi gathered together to make a determined and significant document of their statement of their collective reasons. If it was just some opinion of one man it would not be as important.
Would you call the Declaration of Independence" just someone's opinion, or a significant document?
