imo part of contemporary racist attitudes (from any side of the political spectrum tbh) towards east asia are a lineage from older orientalist beliefs that easia (particularly china and japan) is ancient and unchanging. orientalists of the 19th century saw our countries as places that were stuck in time, decaying through inertia and opposition to "progress" (which, of course, would be brought to them by opening themselves to the west).
modern-day east asia... enthusiasts [polite smile] i'd argue cultivate a descendent of that thought. those who don't assume easia is just like their home country instead treat easia like it's insular from history and the rest of the world, as though our countries have not been historically imperialised and are not bombarded (like the rest of the world) with western viewpoints and american mass media. as though we don't go through societal change through our own efforts and of our own accord.
but no - east asia is a holdout against the tide of modernity. culture is not the background and context against which we move, but traits of each individual's character. an unruly child isn't just upset because his parents aren't buying him candy, he is rebelling against confucianism, and his parents disciplining him is bringing him back in line with confucian teachings. we are defined by rules, philosophy, and tradition—the more ancient these things are, the more intriguing for our onlookers.
better yet, to be untouched by modernity is to be untouched by its discourses. you know, "japanese people don't care about political correctness, they just write what they want" and "actual japanese women don't mind being sexually harassed" and "japan is homogenous so you can't possibly expect them to be sensitive towards other races." japan is presented as static and unchanging—people don't care because this is how things always were, and this is how things will be forever. it's their tradition. it's their culture.
meanwhile china's rapid societal modernization post wwii is largely regarded in every aspect to have been brutal and barbaric. whether change yields positive or negative results it's viewed negatively, as though it doesn't matter how many years pass or how many steps are taken, chinese people are still backwards and regressive, always socially lagging behind the west. because that is apparently our culture.
and yes this comes from all sides of the political spectrum. the right-wing fanbase which idealizes the unchanging nature of japan, a "progressive" fanbase that assumes japanese people are so tied to tradition and an imagined culture that everything goes back to rigidity and long-established practices, often justifying harmful things in the name of respecting japanese culture. nothing and no one in china can't be explained by saving face and confucianism, which is at all times oppressive, evil, and a source of mystical guidance for chinese people.
being considerate and acknowledging that you might not immediately understand every cultural nuance is good, acknowledging that not every story needs to be personally relatable is good, acknowledging that people are influenced by cultures different from your own is good. but at some point it becomes ignoring the fact that asians are humans who are influenced by our culture in addition to personal experiences, feelings, traumas, ambitions, politics. like just think about how everyone around you interacts with culture and to what degree that informs their actual personality and deepest desires and assume that asians are the same as you in that respect please.
being an asian among easia "enthusiasts" is like there's always this interminable search for authenticity, for what is "traditional," for the "real" japan untarnished by these modern western ideas of feminism, and meanwhile many societal advancements for china are just... ignored (don't you know regressive china is so homophobic that disney can't even portray gay affection?). everyone wants to pull us back through time and explain us through adherence to culture and tradition, as though the modern day and just... simple human experiences don't matter or contribute to our lives. we just gotta be explained by something else, something that makes us other from the west.
