I don’t have a strong opinion on whether it’s allowed for a state to leave or not, I’m inclined to say “sure, bye”. Hawaii on the left (native Independence freaks), and Alaska and Texas on the right are the only states with noteworthy quasi-serious movements to ditch the union today.
Chances are be less than zero if we continue to slide into Obamaism that conservative states would start thinking about this. If it got that bad, into socialist dictatorship territory I’d be on board. But in such an instance I’d rather overthrow the socialists and free the whole country. There’d be a war anyway, I can’t see them letting any state freely leave.
In the reverse, if we conservatives took over and restored small constitutional government and liberal states wanted to leave I don’t see it happening because
A)I think your they would lack the will/ fail to convince the socialist sheep voters that it was necessary
B)Every liberal state has conservative areas/citizens that would resist
C)Things would improve so much economically most people would realize socialism sucks and think it foolish to leave so their state government can raise their taxes and ban gas engines.
But as to Civil War I’ll invite your ire and say I have to think it was not right that they seceded. I hear people say the South left to preserve their “freedom”. But it was their freedom to own slaves they sought to protect wasn’t it? It wasn’t just the principle of the thing (ie damn Yankee Lincoln can’t boss us around). They didn’t seem to care about “state’s rights” when they wanted to force the Northern States to return fugitive slaves. Seems they were very selective about it. Dubbing the Confederate cause as purely a noble fight for freedom looks like historical revisionism to me. I’m not impugning the character of men like General Lee who fought out of love of state but the conflict was fought in defense of a horrid indefensible institution. The modern equivalent would be a civil war fought over partial birth abortion. Which I think the Federal Government has every right to ban.
It was also foolish of them, it provided the only opportunity for abolitionists to actually immediately abolish slavery all together. Congress in fact passed the Corwin Amendment which would have permanently prevented federal intervention in “domestic institutions” such as slavery and left to the states. I surmise if they came back to the Union each Southern state would a have eventually phased out slavery as it became economically unnecessary.
If I were President in 1861 I would have been reluctant to invade the South and I certainly wouldn’t have gone total war on Georgia if I did. But if I were a slave I’d be glad the war took place.
When dealing with socialist/Yankees you have to be ready, because as a group they are haughty and don't like people leaving the tree fort and building their own.
