“There was also that Slavery\Civil War thing on the horizon. Not a valid comparison!”
Unless, of course, there is presently a civil war on the horizon.
Still an ahistorical analogy!
If (and that’s a big ‘IF’!) a future civil war occurs, it will NOT be like the 1861-1865 “Late Unpleasantness”! Issues are different but more importantly it won’t be a regional conflict no state-vs-state it will be urban-vs-rural. The closest historical analogs I can come up with is various revolts against the central government in China.
No good will come of it.
