couldn’t it be argued the Confederacy was the real USA?
No, though they did try to argue it and they lost
If you need to change the constitution
They did it by following the Constitution’s rules for change. The Confederacy tried to subvert the Constitution because they were losing. You don’t get to cherry pick which parts of the constitution matter and ignore the other parts. The Confederacy saw the writing on the wall that the US was going to follow the procedure outlined by law to become a free country, and they decided that the law, the constitution and the entire united states could go fuck itself. There is no world in which the Confederacy is good, decent or sympathetic. They committed treason so that they could continue to kidnap, rape and murder an entire class of people and no amount of “well if you look at it another way” will change or excuse that.
