Game Making: Start By Healing the Player游戏制作：从治愈玩家开始

Your arguments actually make sense, but the biggest problem is that no matter the actual ratio of writers and the Chinese population with nationalism, racism, etc. The government can literally censor until the writer changes to something they like and think is right, I think that's why, besides culture, most CNs have this context of elevating China and demeaning others. I don't have a problem with it either, but it gets bad when it's done all the time and totally takes away from the logic of the novel. For example, there's a novel I read where a guy goes to a world where history and ancestors become a kind of power that allows you to build up your territory and then expand. The biggest problem is that literally every country apart from China is weak in terms of history. The novel literally says that 90% of the world's history and evolution happened or defended from China. The problem gets worse when they continually emphasize this with comparisons of territory, etc. This makes the Mc completely Op and have basically no decent enemies apart from other Chinese dynasties, who don't even fight properly because, they say, the Chinese are cultured and rational.

In short: When the government controls all physical and digital media. The people are generalized until they fit the molds they make and when this is seen from the outside, the entire population is seen as having a single personality, which is not true. I agree with your argument, it's okay to root for something or someone, the problem is exaggerating it and breaking the immersion, which happens a lot on CNs and KNs, but also happens in other countries, albeit more dispersed.

If you want to read something that deals with these issues of excessive nationalism, etc. I recommend "I Became the Academy’s Kibitz Villain ACTION DEMONS" the novel is very good and brings a good reflection on the society.
