It was a war over real estate. Look at all the coastline the United States Government would have lost. The lands. The propagandists turned it into a morality conflict. Made us recite that stupid Pledge of Allegiance. The North invaded the South when they wanted out.President Grant wanted to deport all the Negroes to the Dominican Republic. Abraham Lincoln said he never intended the Negro to be the equal of white people. Remember the riots in the 70's in Boston over integrating the schools? The Yankees didn't want them. They wanted to maintain control.
