Myself, my daughter, my grandchildren and many friends attended Southern schools. I can assure you we were taught the same (incomplete) version of the Civil War as you.
As a youngster I was confused when my elderly relatives (who would be well over 100 yrs of age now and are long deceased) would refer to it as the War of Northern Aggression. I had been taught differently in school.
As an adult I found a personal interest in the Civil War era and began researching. Boy, talk about an eye opener!
Such an unfair name for the war; slandering many Northerners who opposed the military invasion of the South.
I have long thought that one of my American History/Government professors in college had it right. He exclusively referred to the late unpleasantness as "The War of Federal Aggression". As do I.
