I think a lot about how US-centrism is a really big thing, and something we USians commit whether we are conscious of it or not -- because, quite frankly, no matter how much we proclaim to dislike our country or want it to change, or straight up just want to leave it behind, it's already been deeply intertwined into our personalities.
But there's also that other factor where when it comes to fandom, we end up writing AUs set in the USA, because, well...that's still our home? That's what we're familiar with? So of course I want to play around and reimagine WangXian as diaspora Chinese growing up in New York, just like me. I think it'd be really funny to reimagine Arno as an exchange student who has to deal with NYU kids out here (I pity the man, NYU is an elitist nightmare). And if Tumblr is a US-based site, where most of us end up gathering, that's just math, right? There are going to be a lot of USians here writing about our experiences in this country, because they're the things that immediately affect us the most.
I don't think it's inherently bad to want to reimagine characters in the world we personally live in, but we do have to ask ourselves some hard questions about why we want to take these characters and put them in a setting that we are comfortable with. Would we appreciate them all the same if they were in a setting unfamiliar to us?
And if we were on a non-American site doing the same thing, and the people on that site got mad at us, how would we react? We have to be honest with ourselves.
This is not permission to whitewash characters.
If you're writing an AU with characters of non-American origin, do your research on their cultural norms.
Also, the USA is the "melting pot" or whatever the fuck you wanna call it, right. So is this character going to be an immigrant, a tourist, a tenth-generation American, or a second-generation American from another country's diaspora?
*Or are they Indigenous? In which case, what nation are they from, did they grow up on the rez, elsewhere, and what relationship do they have with their family and identity?
We should still think outside of our country. Realizing and acknowledging that we are raised to be ignorant of the world, and that our country holds a cultural Monopoly (i.e. our fucking media and entertainment are EVERYWHERE, and my roommate from Vietnam knows iCarly as well as I do, and I know someone from Nigeria who grew up on Johnny Bravo, just to name a few examples) are only the first step. We need to deprogram and see the rest of the world as a place that exists outside of us while still being affected by just how sprawling our influence is.
I'm an immigrants' kid who grew up among other immigrants' kids in New York (note, I say "immigrants' kid," meaning I am explicitly not saying we immigrated, only that our parents did. People assume I came here just because I'm not white, which is some racist bullshit).
I have lived on other continents.
MDZS is easy for me because it's my culture. I've written them as diaspora Gen Z kids, Chinese people who grew up in mainland cities I'm familiar with, and in the canon Ye Olde China (Tang-dynasty-ish, but also a Ming-dynasty AU) setting.
I write French Frye in modern-day Paris and London very easily because as a USian, we're taught that "world history" is just "Western and Central European history." We're a Eurocentric society. Also, I've been in those cities and know people from there.
I struggle with writing Ratohnhaké:ton even though he is literally Indigenous to the land I grew up on (Kanien'kéha:ka were from upstate New York, just a day's drive from me, before colonization forced them to move further north). As a USian, that means I was taught the colonizers' attitude towards Indigenous folks, and despite all my research and talks with Indigenous folks to learn to be better, I will eventually trip up and accidentally say something racist or culturally offensive.
This isn't going to stop me from writing fanfic about him, but I'm gonna do my due diligence and consider the circumstances he would be in in a modern AU.
Yes, I want to write a modern-day AU where he goes to China and trains with Shao Jun, because I'm Chinese and I think that would be neat.
When I read modern AU MDZS fanfiction, I can tell who's not Chinese when I read about WangXian living in a house in China. I cannot emphasize how different the apartment-to-house ratio in most major Chinese cities is from the USA. I don't find it offensive, it's just a really strong tell.
If you're writing an AU set in NYC and there isn't a single "yerrrr" in it, you've already outed yourself (this is a joke).
