The concept of cultural appropriation has always been so hard for me to understand for whatever reason. And yes, this is obviously related to my privilege, I get that.
I do understand though that people of a marginalized culture might be pissed off if they are constantly portrayed wrong in the mainstream culture. And I am sad that whenever someone talks about this, they face huge backlash. Disagreeing opinions are fine, but it's always sad to see people not even trying to understand where they're coming from. People yelling "it's fiction, fuck off!" really doesn't help, and attacking the speaker (which isn't really happening here fortunately, but it does happen in general) is just horrible.
That said, I'm still heavily inclined to agree that Rowling's writing here is fine. It's hard to see any disrespect in there, as it's not portraying Native Americans or their tales in any bad light at all. It doesn't use racist caricatures or anything like that either. It's a very similar treatment as what Rowling has done to other cultures - take what they have, but conform it to the fantasy world.
She could've of course sought council from Native Americans, but honestly, I don't really hold it against her that she didn't. It would've been nice, but it's not something that should be expected every time a creator wants to take things from a culture, even if it is a marginalized one. Research is something that should be expected I'd say, but it seems that the amount of research isn't the problem here, as Rowling didn't even write much about it and what is written is based on their myths/religion, but it's just conformed to her magical world.
Native Americans are of course free to offer their criticism still, but I just don't see why I should have any sympathy towards it. I can understand where it's coming from, but I don't agree that it's fair criticism.
Some of the criticism also just seems really strange. Like the tweets of Johnnie Jae in the article in the OP:
Jae wrote: This isnt us saying that Native people cant be wizards or magical beings, but that @jk_rowlings attempt is unacceptable & disrespectful because @jk_rowling has based her native wizards off the same racist stereotypes & miseducation that JM Barrie used in Peter Pan.
We're saying that there is problem when non-natives continue to use outdated & racist stereotypes as the basis for their native characters"
I can agree with the latter part when generally speaking, but when talking about this particular case, what racist stereotypes and miseducation is she using/portraying?
If someone has any idea, I'm open to hear it though. As I said, cultural appropriation is really hard for me to understand, but I do try.
