What evidence is there that the south is justified in calling the Civil War the War of Northern Aggression?

by imarokk

In case the title wasn't clear, what do people in the south or southern textbooks use to justify calling what we call the Civil War the war of Northern Aggression?

I think you've been downvoted because the causes of the Civil War are covered in the FAQ of this subreddit, but I feel this question is slightly different than "was slavery the cause of the Civil War" so I wish that this question had become more popular.
