No need for a big pot of word soup. We did not have a Civil War. The Confederacy was not fighting the Union over the control, molding and changing of this nation. The Confederacy fought to be free of and from the Union. This was the Second American Revolution. It was both legal and moral to do so; just as much as was the First American Revolution.

“When Tyranny becomes Law, Rebellion becomes Duty”

Colossians 3:17 (New King James Version)
"And whatever you do in word or deed, do all in the name of the Lord Jesus, giving thanks to God the Father through Him."
