What a load of CR*P.
You need to take a history course and learn about the South from a neutral source. Slavery wouldn't have lasted, even if the South had won. It just wasn't economically feasible.
As for Lincoln, well, he got what he had coming.
I have read sources from across the board for fifty years including those beloved by the Defenders of Slaverocracy.
There is nothing important that hasn't been amply handled.
The Rebellion was started by men who had worked throughout the 1850s to destroy the Union and protect slavery. There is no doubt about this. Nor is there any doubt that they would do ANYTHING to protect slavery and that included expansion into the Caribbean, Mexico and Latin America. Fortunately for the world America had a leader who put a stop to their insane plans.
Slavery was an economic impediment to the non-slave South but that didn't matter since power was held by the Slavers and THEY profitted. What did it matter to them if it impoverished the entire region? They cared only about ONE thing, slavery.
