Where Chinese and Korean culture is absolutely equal is in that they are equally diffrent from the Western traditions of America , so they are equally easy to misunderstand.
I have known only a few Chinese and Korean Americans who were born overseas and are partly assimilated , they seem bemused at how strange we are as they slowly continue to assimilate.
No question that Koreans have cultural features unique to Korea, no argument that China has a lot for Westerners to learn from. Diffrent from each other , equally far from their origin, immersed and coping with an exotic and sometimes perplexing alien culture , mine.
Why do we call anyone "Asian"? or "African"? We don't think of "European " as a complete or adequate description for a Frenchman or a Dane.
My theory, we are better educated in European history. Most of us know that there is a lot of difference between a Swede and an Italian, but we have spent less time learning the history that produces the difference between a Cambodian and a Korean or between a Kenyan and a Congolese.
Oh well , we can't learn it all, but we can subscribe to the "National Geographic".
