Thing is that nobody would present it that way in an academic setting. This kind of thing would require approval from the dean or department head, and neither would probably want to chance the kind of bad publicity here. I'm taking a Holocaust class that will include viewings of Jud Suss but this isn't to present it as anything other than showing what Nazi propaganda actually was.

You're right that it was inaccurate, but it's also worth noting here that the real Civil War will never make it into your average textbook, not least because adding in the blunt reality that it took a huge number of white and black Southerners to provide the Union with manpower sufficient to win the war and the degree to which the Confederacy had elements of a military dictatorship and multiple mini-civil wars would lead to a picture much more like the Lebanese Civil War than the traditional narrative. It'd be too nightmarish for US ideology to allow in terms of actual courses.
