Consider, though,
@RangerWickett, that art can oppose -or- reinforce social structures through it's political impact.
Luke fought Space Fascists without changing people's minds to suddenly hate fascism... but his actions reinforced the anti-fascist structure of western society at the time. Just because it wasn't spreading a message of reform doesn't mean it wasn't spreading a message. Same with Indiana punching Nazis... Though it's also worth noting that Neonazis were having rallies in the US in the 70s and 80s.
Which is why the Blues Brothers hate Illinois Nazis. So that may have even been an overt political stance against current events, at the time, viewed retroactively as being "Not Political" or otherwise not having a message.
And a game without queer characters in the world -also- spreads a message, unintentionally in most cases, of exclusionism. Same thing with a game where everyone is white. But these positions are rarely viewed as a matter of politics and instead seen as a default state upon which diversity and politics are imposed.
Gargoyles is apparently a great example. The show has hispanic and native characters, black characters, scots, brits, whole nine yards. People I know loved it as kids for being so apolitical. But if you pitch them the show without specifically saying the name, they call it "Woke" to have a female minority detective as the monster's friend.
Like... Eliza Maza was just as political a decision in the 90s as it is today. Possibly -more- so. We were just kids and didn't internalize it that way 'cause we weren't aware of politics.
Honestly... that might be the true crux of the whole "This stuff wasn't political in the good ole days!" problem. Yeah, it was... you were just too young and/or unaware of politics to realize it at the time.
