Sorry to reply to a days old thread, but if you haven't seen the reporting on openly-fascist groups like Patriot Front and openly-nazi groups carrying swastika flags in marches (in the USA for both examples), you're likely only getting a very biased news feed. Or the Terrorgram extremist online group trying to recruit kids on Roblox. Or the openly white-nationalist guys starting "youth clubs" that are like gyms and scouts trying to recruit kids.
I'm plugged into a lot of media that isn't typical USA pablum, so I learn a lot about extremists. But the first two examples get play in mainstream news media and even the others appear on non-fringe (just not mainstream) sources, like the Southern Poverty Law Center and such.
Of course you're going to get nationalism-tinged anti-fascist propaganda from the US Dept. of the Army in 1945.
There are large voting blocs who need to hear and comprehend the message of this film that happens to be propaganda, right now.
