“States are sovereign and have the right to unilaterally secede. That is precisely what each of the 13 colonies did just 8 years before the constitution was ratified”
You’re calling the revolution secession?
The Founding Fathers knew well they were committing treason.
It was justified.
The revolution was secession. Yes it was justified. So was the secession of the Southern states in 1860-61. Both were caused by the same thing - taxation without representation.
(and yes the British offered the colonies some seats in Parliament - just not enough to protect themselves from being economically exploited for the Mother Country’s benefit).
When people feel that they are being taxed for others’ benefit and that they do not have effective representation - that is enough representation to protect themselves against ever more money grabs by a government, its hardly surprising that they then decide they’d be better off going their own way.
