I mean... if the story was written by Asian authors, it's valid, right? Doesn't mean it's the ONLY valid story - as you say plenty of Asian people do not relate to these tropes. But many do. I went to a school that was about 95% Asian. And all my friends could relate to the "overachieving Asian kid, wanting approval from overbearing mother". TBH I could relate to that trope too, despite not being Asian. Just because something is a stereotype doesn't mean that it's not a common experience in real people's lives nonetheless. I think it's important that we don't have that be the ONLY narrative.
