Total BS. The South revolted to defend slavery that was the ONLY reason. Slavery was the dominant force there and EVERYTHING had to support it. ANY opposition to slavery was driven out of the region. NO newspapers, magazines, books were allowed if they spoke against slavery.
Federal influence on the South was negligible particularly since Southerners had controlled the federal government for its entire existance. But Lincoln's opposition to slavery expansion was too much for the Slavers.
"Slavery was the dominant force there and EVERYTHING had to support it. ANY opposition to slavery was driven out of the region."
Your BS detector is highly suspect. I'm sitting in a town right now, in NC, in an area that was originally settled by Quakers, who abhorred slavery and were quite outspoken about it. If you'd ever been "there" as you so revealingly put it, you'd realize that "they" were far from monolithic in anything... religion, support of slavery, wealth, ancestry, you name it. You'd probably be astonished to see Levi Coffin's false-bottomed wagon, used to hide the runaway slaves he was transporting.
Read a little before you spout off on something you so obviously know nothing about, please.
It was about State Rights with the South.
