[quote=“mod lang”]China, as like Europe and India, is not a small, racially homogenous nation but a large, ethnically & linguistically diverse subcontinent. Just as there are subdivisions between Indians and Europeans but an idea of an over-encompassing concept of “India” and “Europe”, so the same should apply to “China”. A Dane and a Greek look totally different, have totally different cultures, speak totally different languages, but are both Europeans. Taiwanese are a legitimate subdivision of the Chinese family of ethnicities. There is no one Chinese ethnicity, or even spoken language, but a multiethnic/linguistic framework. A common written language and shared history & certain common cultural values unite the various Chinese, just as the Latin (or Cyrillic) alphabet & Judeo-Christian/Greek philosophical heritage unite Europeans. China is a more solid foundation than the more recent and more artificial concepts of the EU and India, since it’s been around a lot longer.
Besides, nearly everybody has multiple identities. The ethnic, linguistic, national, religious identities are all separate identities.
There are ethnic Chinese - huaren. Not all of them live in China, nor necessarily speak Chinese (many ABC’s, for example). 華人
There are citizens of the People’s Republic of China. 中國人
There are those that speak one of the Chinese languages.
There are those that follow one of the traditional Chinese faiths/philosophies and are culturally shaped by the traditional Chinese ways of thinking. Just as once a Catholic (or Mormon, Baptist, etc.), always a Catholic, no matter if in adult life you become an atheist, so Confucianism/Taoism/Buddhism cuts into the Chinese mindset to the core, no matter if intellectually they reject traditional Chinese superstitions. For example, if you shunt your parents off into a nursing home to get them out of your hair, then culturally you are not Chinese; lack of excessive filial piety is a Western value.[/quote]
I think that a number of the points you have made are contestable.
See the complete dissection of these issues in Burroughs, DeLislet, Mickelmeier, Daltongroing, Attalyip, and Cakamunger. Those are the standard reference works on the subjects you have mentioned.
