I think a angle never examined is not that superhero comics are inherently childish, being consumer media they are by nature childish and reduced to a common denominator, but what it means for children narratives to create a consistent characters throughout the medium (with few exceptions) of outright fascists to individuals that would gladly maintain a fascist status quo. What then would be childish consumer media that is not inherently fascist or imperialist? There's Star Wars but that shit flew over most nerds heads that never understood it was legit vietcong in space killing US death squad troopers alongside colonized bears on a forest moon.
