Anyway, this leads to a feeling (a logical one!) of possessiveness over the tidbits of culture that you can claim for yourself.
2. The nuances of cultural erasure for a canon that was created by the dominant ethnicity and culture of Somewhere Else. As point 1 says, I highly doubt Chinese-from-China would feel as possessive over MDZS/CQL as diaspora fans do. They have many canons that reflect their world; as diaspora, there is relatively few canons that speak to the Chinese diaspora experience. So we attach ourselves to the things we can see a glimmer of ourselves in, in familiar faces, even though we aren't really their target audience.
I personally don't like most modern AUs or really, fic that gets too removed from the Chinese roots of the canon and just /feels/ wrong. It's just not what I enjoy reading. But I'd argue that it's way more erasure to celebrate [insert vaguely often American modern AU here] through its ubiquity and influence on the fandom. I know I fall more on the "this is a transformative works" fandom side of things generally, though I also know that fic and fandom can be deeply racist. But blanket bans on what kind of transformative works are permissive... MDZS/CQL are out there in the world! We can't erase it by any fanworks.
I do fully understand /why/ people are uncomfortable with certain transformations, I just think that in the absence of criticism of transformations that are similar, it leads to point 3.
3. I am so, so, so uncomfortable with anti-Semitism in a world where the alt right is resurging. Adding to the previous tweets I made a while back, characterizing Jews as "greedy," "taking over" are clearly dogwhistles. Please, I beg you, do not. The double standard where Christian AUs don't get backlash? Also seriously anti-Semitic.
As a nonreligious person who grew up in the US, where Christian Chinese are common, I absolutely 100% really do not like Christian AUs. And hey-- I can skip them when they're tagged. The fic getting backlashed was tagged as AU and Jewish from the very beginning.
In conclusion, I don't really want to be ~discourse all the time~ like I feel like I've been recently. I wanted to do two things: a. to push back on the narrative of "you're pushing out diaspora folks!" a bit and b. leave an opening for my ideal, a more nuanced discussion about why certain things feel like erasure and certain things do not. I think it would be revealing.
