"But 'The South Was Right' school goes far beyond honoring the Confederate dead and actively demeans the cause of those who fought on the other side."
Well, respectfully, duh. If the South WAS right, it appears they have a bit to complain about.
"The demands that groups made for self-determination would tear apart self-governing societies, and secession would be a warrant for perpetual war and all the anarchy and tyranny that war brings."
Again, respectfully, do you even hear what you're saying? It's preposterous. The argument that the essence of lawful self-government is the denial of self-determination is so surreal and Orwellian as to leave one dumbfounded, and the notion that peaceful secession leads inevitably to war is, frankly, equally so. If a State can secede lawfully, then there are no grounds for war. It was precisely the attempt to STOP States from seceding that led to war--just as in the case of the American colonies, when they seceded from Great Britain.
"The idea that state sovereignty equals the sovereignty of the people of the states equals freedom is another that can be called into question."
Then equally so national sovereignty when compared against global government.
