I don't know anything about Fallout but I just want to say it's very funny when fascists claim that Fallout is pro-US and anticommunist because there's a cool robot that says death is a preferable alternative to communism.
Maybe there is a larger conversation to be had about the phenomenon of reactionaries taking media that is satirical of reactionary behavior like Fallout, Fight Club, Starship Troopers, and American Psycho at face value. Most of the discussion of this phenomenon is about how fascists are not smart enough to understand that the media is making fun of them, but isn't it a case of "if it's stupid and it works it isn't stupid?" It seems like we live in an age of nihilism and contrarianism. If the media tells people that fascism is bad but doesn't offer an alternative (liberalism doesn't count because we live in it and it visibly sucks) it makes a lot of sense that reactionaries take advantage of the contrarian instinct to say, "what if bad things are good, actually, and you just need to stop being so soft?" which is transgressive and, in a way, more innovative than recycling liberalism.
Just imagine how you feel watching Death of Stalin when Zhukov does the thing with the jacket. You're not supposed to think "Hey that's General Zhukov who is awesome because he killed a bunch of Nazis! I love this guy!" you're obviously supposed to think he's another communist bootlicker like all the other characters in the movie. And every communist watching that movie obviously knows what perspective it's written from. Does it make it any less effective as a vehicle for propaganda if a communist can show Death of Stalin to some friends and use it to break the ice on the topic of Stalin? Because that's how fascists use this type of media, and it's undoubtedly pretty effective. When smug leftists like us show up to berate their lack of media literacy it only serves to reinforce the transgressiveness and their own smugness.
