I can't decide if I should post the "wait, it's all the failures of capitalism?" or "wait, it's all systemic racism?" meme, cuz it's wait it's all both (always has been).
Are there even any indigenous people in Tarzan? I haven't read the book, but from the movie I only remember his gorilla buddy and the little elephant. I think Tarzan is more about rebelling against civilization in general, instead of colonization in specific (which James Cameron's Avatar is). It's very post-industrialization in that sense.
Edit: Whoops, just read the synopsis on Wikipedia. I don't think Tarzan is the white saviour you're looking for...
Looking at it now, I see citations for the essays, but not for the factual claims made by those essays, so I hope the editor who wrote it didn't take their word for it.
One time I unmatched someone from a dating app because the second avatar movie was coming out and they said that it was weird of me to say that the alien people were supposed to represent Native Americans because "they're just blue aliens why would you compare them to real life?"
