One more time. Civil War is a fight between two factions for control of the govt. The South was not fighting for control of the govt. They wanted to secede, be left alone and have their own government. The Union/Northern states invaded, subjugated, occupied and forced their govt on the South. You can thank Abe Lincoln for the police state government we live in today. He was responsible for destroying states rights.
You are simply making up a definition of civil war to fit your opinion on ours. Civil wars can be fought for any number of goals, sometimes limited, sometimes for complete power. But the one factor that makes them civil wars is that they are fought between citizens of the same country.
I'd put that on the 14th Amendment, actually.
By no small surprise Merriam Webster dictionary has the same definition for civil war as what Hugin offered. Although I prefer “The War Between The States” the “Civil War” is entirely accurate and the northern aggression foolishness is sheer nonsense..
