GaWB,
I'm about half way through a 3 volume Biography of Patrick Henry "Patrick Henry: Life Correspondence and Speeches".
It's quite amazing to understand what he and the Colonials went through and compare that to the first paragraph of your last quote.
It should be noted by all, and this is irrefutable and of utmost importance in seeing the legality of what the south did, that the southern states did peacefully and lawfully withdraw from the Union. They followed the same avenue that our Founding Fathers followed. They, through peaceful and lawful appeal to their magistrates, withdrew their countries from the greater union.
The very avenue and mechanism of their withdrawal removes all accusation that they acted in hast or anger. Too much time passed for their decisions to have been based on testosterone responses. Like their Grandfathers these men knew that the price of freedom and self rule was at stake. It matters not the reasons for their leaving, it matters not their purpose in leaving, it only matters that they left legally and peacefully. They felt it their duty to posterity.
A sovereign nation was then invaded and it's will bent to meet that of the invader. Reconstruction and it's evil is all that is needed to support that idea.
