One thing about these secessionist movement types: do their promoters ever recognize the right of subareas in these states have their own right to secede?
Do "blue" areas of Texas have the right to secede the state? Do the interior red parts of California have the right to secede the state?
Same arguments could be made for both, I would say.
I don't believe the proponents of secession ever truly think out the ramifications of secession.
Okay, it's ten years from now, and it has been established by an act of congress and a change in the constitution that states are sovereign entities and can leave any time they like.
So some states get a majority or whatever number of adults to effect secession, and they leave the union.
They have to come up with their own laws, regulations, trade agreements, currency, etc.
But what if, down the road, a majority in the separated state decides they don't like being an independent country and want back in? Should the U.S. let them back in? Some pro-secessionist people, like the late conservative pundit Joseph Sobran, thought that would be an excellent idea. States could leave and come back in whenever they felt like it.
Actually, it's sheer lunacy. Why should the U.S. adopt a system where states decide at various points in time to leave or re-enter the union? Lunacy.
