So many problems arise in this discussion from the failure to distinguish among three different categories: ethnicity, nationality and geography. Then it gets more confused by the overlapping names. China, for example, is a nation, but not all Chinese (nationality) are Chinese (ethnicity), and not all Chinese (ethnicity) are Chinese (nationality). East Asia and South Asia are places (geography) that contain people of numerous nationalities and ethnicities. "America" is a place (geography), but many people think of it solely as a nationality (United States of America). "Indian" can be thought of as a description of a person from India (nationality) or a representative of a particular religious group (Hindu), but in America it is frequently used to describe the natives who were living in North and South America when Europeans arrived (ethnicity and geography). Trying to make valid generalizations about individuals on the basis of membership in such confusing groupings is pretty difficult.
