Ultimately, the real reason for the tragedy was the refusal of the Federals to allow the south to secede. State's rights and holding the union together was paramount in Lincoln's mind.

Everything else just added fuel to the fire and gave you a reason to hate.
I don't really care enough about the south one way or the other to hate it. But that doesn't mean I'm willing to sit back and watch fairy tales posted as fact.
