are you saying that everyone thinks the Civil War was only about slavery? It never was, and anyone who thinks so is seriously misinformed. It was just as much, if not more, about economics (of which slavery certainly played a part); and ideological differences that had been smoldering since the founding. And are smoldering still.

Has history been "rewritten"? Possibly. Likely, even--it's an inevitable process condensing historical acts through the long lense of hindsight. But I think the problem is more ignorance--the facts are there if one cares to look.
