Fort Sumter belonged to the State of South Carolina? Is that your argument?

You are proceeding from an incorrect statement. The land had been purchased by the Federal government. The State of South Carolina had not bought it from the Federal government, therefore it still belonged to the Federal government. (Secession tends to get messy when dealing with who owns what; South Carolina chose the thieves' option, which was guaranteed to start a war eventually.)

I am firmly of the opinion that the War between the States was due to an overabundance of lemon taffy in the North, and a shortage of lemon taffy in the South.
