The "most ignorant and racist person" I currently see is you.

This being stated, I do not deny that many Chinese people are ignorant, and some of them may be even rightly called racist. You'll find such people everywhere in the world, not only in China. Even some black people, for example, may be rightly called racist. In the latter case, they simply return what they were given first by certain parts of the "white race".

Maybe you should tell the Chinese about their isolationism The most ignorant and racist people on this planet.
