Except you seemed to imply up above that the right to self determination overrides just about all. To whom need I make this “argument”?? To the mayor of my town? To the governor? To president combover boy??
Historically speaking, a “compelling argument” in the case of secession involves weapons.
James Clavell put it nicely in his novel Shogun:
Toranaga: “There are no ‘mitigating circumstances’ when it comes to rebellion against a sovereign lord!”
Blackthorne: “Unless you win.”
Toranaga looked at him intently. Then laughed uproariously. “Yes, Mister Foreigner…you have named the one mitigating factor.”
