"In fact, it was actually necessary for politicians to organize campaigns in the North to stir up the idea of fighting to keep the southern states in the Union."
I agree.
"The initial response of most northerners was that they were actually glad to see them go due to the fact that they had always leached off the north economically. It was only after longer reflection that the people in the North started to realize the kinds of trouble and grief the inane idea of releasing the incompetant southern states into the world was likely to bring."
ROTFLMAO! If that's the case the North should have let the South go. Then the North would have enjoyed all those millions that had been "leached" off by the South. Your comment makes about as much sense as a doctor advising a cancer patient to forego surgery or chemo, and just live with it, even though it kills them.
