Neither counties nor towns have special recognition within the constitution. But the states have powers that the federal government does not. I would argue that if it is the will of the people of a state that they leave the union, then the constitution does not expressly forbid this action, and therefore it is a lawful action.
Of course, tyrants believe that might makes right, so in 1861 there was a war and the legal question was eventually settled in favor of the victor. But I still say the CSA was on solid legal ground.
I have found that appealing to logic never works when dealing with the fascist mindset. It appears that some didn't just drank the 'state-ist' Kool-aid. No, some have clearly main-lined it. Is there any wonder how an educated and sophisticated Germany bought the Nazi Party Line? May their chains lay lightly upon them.
I offer a link for the federal boot lickers on FreeRepublic, that they can try to educate themselves: Anti-Federalist Papers
I dissagree. The war settled nothing except that might makes right. Legally Texas v. White decision of 1868 did not settle anything either. IMO Texas v. White decision created Constitutionality where none existed previously.
