If your objection is to a required size of the population, then I will put your concerns to rest. The Southern population was larger than the population of the Colonies when the Colonies left the British Union.
If your objection is that the desires of loyalists ought to override the will of the Majority, then I ask you what is your position in regards to the British loyalists when the colonists broke from the British Union?
This sounds like another example in which both positions cannot be true.
I’m not pretending that there was anything “legal” about our declaring independence from England. We were challenging the existing government. And, we expected a fight. And, we got a fight. And, we won. We overthrew the existing government in the Colonies.
BOTH were decided by force.
I am suggesting that the next time someone wants to secede, that they try a different approach, an approach like Scotland pursued. Try it.
