Geesh, no, it’s clear from the RevWar they were willing to break off from something they didn’t get along with anymore. And also clear they believed in states’ rights, else there would be no 10th A. Never mind most of those people really felt the biggest connection to their own state, not the nation. That continued largely all the way down to the “CW”, such as Lee unable to fight against his own home. And largely why people did side based on their home; not nearly as unpredictable as the RevWar had been, not knowing if your neighbors were friend or foe.
Totally false.
The 1776 Declaration of Independence had nothing to do with "getting along with anymore".
Benjamin Franklin spent 16 years in London trying to negotiate better conditions when the colonies "didn't get along with anymore".
By the time Franklin returned to Philadelphia in 1775 it was way, way beyond "getting along" -- the Brits had already declared Americans in rebellion, a declaration of war, and had begun to wage war against us.

Sure, but no Founder ever proposed or supported unilateral unapproved declaration of secession at pleasure, which is what Deep South Fire Eaters began in December, 1860.

No, in fact there were huge regions all over the South of anti-slavery Unionists, from Western Virginia to Eastern Tennessee, Western NC, Northern Alabama, Northern Texas & Northern Arkansas, plus vast majorities in Missouri, Kentucky, Maryland & Delaware.
In total, Confederate states alone (not counting Border States) provided over 100,000 white troops to the Union army, plus another 100,000 colored troops.
So there were very often no clear dividing lines.
