...And it wasn't the incoming Lincoln administration either....

Lincoln ran on a platform that included limiting the extension of slavery into the territories which, given the events of Kansas, wasn't that unreasonable a position....

To note, Richard, I'm not the original poster who said "The North was the aggressor in that war."  I'd think that's a far more egregious example of picking a "'good side' and a 'bad side'" there -- if not a complete rewrite of the historical record.  Looking at the events leading to the Civil War requires that you pay attention to the detailed timeline in the run-up to Fort Sumter.
