You are comparing our revolution that formed the USA to the confederacy. Sorry, you lost and the USA won. We honor the men who died defending the USA, not the ones who were killing and maiming our soldiers.
"Our" soldiers ? It was Union soldiers who CAME HERE TO THE SOUTH, who were killing and maiming OUR soldiers, in Florida, Texas, Georgia, Alabama, etc.
Yeah, I'm comparing the confederacy to our revolution. Both are examples of secession. So if southern secession was "treason" as you called it, then US secession from England would be treason to England, right ? Right ?
