Beyond its historical accuracy and greater precision, this term has an elegance of expression exceeding that of "Civil War".
On the other hand, "War of Northern Aggression" is not only historically misleading but it has an abrasive ugliness of style. There is also an assumption in the use of this term that "northern aggression" was bad. It was only bad in the same sense that American aggression against Hitler was.
Hooray for northern aggression!
Lest you yankees get too far ahead of yourselves demeaning the South, I call out your obvious jealousy for all things southern as indicated by the “Hitler” reference when discussing the South and the Civil War.
Putz.
