Is the issue about the Southern leaders and statues versus Northern leaders - I do not think so.  It is interesting that OUR country''s founding fathers were the "traitors" to the British crown.  And really, the idea of a single country as opposed to a union of sovereign states was not even in the Constitution; much less that the federal govt was empowered to make war against its own people.  So many issues from history and all viewed with eyes that are (adapted) to the manipulations from our current society.
I guess throwing stones, reviling, and rebellion are today's methods of communicating.  
I also guess that a federal (or state, or local) govt that demands (through threat of armed force) that people work and turn over large percentages of their labors, and wealth from their labors is not viewed as slavery today by all - just some.
