Interntaional fans, you don't have the understanding of the context to comment so please refrain from doing so. It's very complicated and there are historical reasons why Jp/Kr/Ch relations are this messy. I'm happy that Sa-tan wrote about it, but I understand the other side too.

It has nothing to do with fragility. And I don't talk about it much, but there are good reasons why I keep the fact that I speak fluent Japanese from my (very traditional) Chinese family. If my grandmother who lived through WW2 ever knew, she would be rolling over in her grave.

Because there is the misconception that it's all about WW2. Perhaps it's worth going to read about the last few decades. Fans are obviously not historians or east asia political scientists, so have humility. Relations have also stayed complicated and messy for many reasons.

For those asking what you can do: Just say that you support her, you love her, and that you like TWICE and FANCY. There is absolutely no need to wade into the politics because you come off as being ignorant and will not be listened to, or help anything.
