Why do people immediately blame Chinese people whenever they see a post they don't like?

‌

Among the users here, whenever someone expresses dissatisfaction regarding China, people respond with, "Then you must be Chinese..."
I mean, does that imply Shinsegae Group Chairman Chung Yong-jin has a Chinese grandfather?
His stance wasn't even for economic reasons; he was shouting for the destruction of communism, and then suddenly people claimed China didn't apply to his comments.
This is exactly the level of your logic.
How are you any different from the far-right trolls who call someone a "Joseon-jin" just for defending Korea?
It reminds me of the late President Roh Moo-hyun's famous words.
You should be ashamed of yourselves.
