I actually have a problem with using "Asian" as descriptive of people. Asia is the largest continent with almost 60% of the world's population. It includes such diverse countries as Turkey, Russia, (east of the Urals), Armenia, Iran, Saudi Arabia, India, China, North Korea, Japan, Vietnam, Indonesia. There really is not much of a common culture across all those, nor is there a common ethnicity or language.
To me, Asian just seems a word that was coined by British, French, German, colonial empires to describe something "other" and to lump a bunch of peoples and cultures together.
