Secession did not destroy the union - the remaining members carried on as before. But, forgetting about 2005, what about 1788 or 1789? If a founder stood an announced to all present in convention, that 'if we are unsatisfied with the proposed [national] government, we can renounce it, this is an additional safeguard to our state', would you consider them to be a crackpot? What if they stated that 'a power remains with the state until it is delegated'? Is that gentleman a lunatic? Are they insane?
It would not have anything to do with the fact the 'Confederate' traitors were resoundingly defeated, thereby preventing a separate, expanded slave empire? Who needs little factoids such as that - right?
