Agreements have their methods of resolving disagreements. Unions have them too. Rather than have the King of England resolve local disputes (that didn’t work out well for Scotland) a federal court system was instituted.
The rebels sought to resolve issues on the battlefield rather than in court. They lost.
Exactly. But you can lose big in court as well. Ultimately what the court says is irrelevant if the people wanting to secede are to have any self-determination. This issue is about whether a state even wants to recognize the authority of a federal court. Asking a federal court to make that decision is absurd.
But throwing down the gauntlet on this is stupid. It is an emotional outburst that is more likely to doom your cause than bring it to realization.
