No more silly than many of yours.
Ft Sumter is not even slightly comparable to our bases in California.
But by the standards used by the Confederacy all military bases would immediately become the property of the nation of California, without compensation and without discussion. If the U.S. tried to retain them or supply them in any way then they would be the aggressor in the war that followed. Right?
I have a lot of silly conversations with you. I’m not going to entertain this silly one.
