Try that with your wife. She'll end up with way more than half your stuff.
If the South really wanted out, they could have worked through congress to dissolve their relationship with the other states on an amicable basis and seen to it that all debts and obligations were satisfied. They chose instead to grab all of their stuff along with the stuff that rightfully the other states had a claim on and play macho and say 'come and get it.'
Well the other states came and got it. Tough s**t.
Fort Sumter is a perfect example. It was a man-made island, built entirely by the Federal Government over the course of thirty years (at the insistence of the South Carolina delegation including your patron saint of disunion, J.C. Calhoon). It was a major boondoggle for those 30 years that pumped money from all the states into the Charleston economy.
Suddenly, South Carolina claims it as their property when they paid next to nothing for it! It would not have even existed left up to South Carolina. Even the wimp Buchanan who loved you slavers would not go along with that.
And how about the millions the Confederates stole from the other states in taking over US arsenals, mints, forts and other federal facilities even before the first shots were fired at Sumter? Your sainted ancestors tried to run away with the store because you thought those dough-faced mechanics from the North would never be men enough to fight you. Well, they ended you kicking your grand paps ass and you are not man enough to get over that fact.
Many of them were impressed into the Union army against their will, (What were they fighting for again?) and many of them were sent to die in the South because they always needed more men to throw against Lee's meat grinder.
You should read more history, and not just the stuff you can find on Wikipedia.
You win the internets for the day!
