if that was their goal, it would have been better to never explain the conflict in the first place. just start in medias res, with asemic dialogue and references.

Quite different from all the documentaries my dad was really into about the US civil war. (Many of which lionized the southern generals.) Or annoying "states rights" points that he seems to have picked up from some YouTube gutter.
