You can't have a good war movie that's also a parody, because people just take the cool/funny parts as approval of the atrocities.

And nothing is safe. You'll have sitting American Congressmen putting out hacked up Attack on Titan videos with zero context, because David v Goliath is just a cool image and you want to make teenager shock troops fighting hideous (((monsters))) on top of a big wall look Based.

Your enemy is always an existential threat and doing war crimes is incredibly cool. So yay fascism!
