I'm posting the following as a comment on the use of "Oriental." I don't necessarily agree with all of it, but I do think it is of interest:

OK, so a long time ago, people in Europe used to refer to everything to the east of them as the Orient, including for example the Middle East, since orient means "east". So far, so good. This mysterious area was the source of all sorts of wonderful things like silk and spices, so the Europeans attached also sorts of exotic, mysterious connotations to the Orient. As Europeans gained a better concept of world geography, they eventually used "the Orient" and "Oriental" to refer to East and Southeast Asia, where people look "Oriental" in our current usage.

Anyway, that usage of "Oriental" has survived a long time, and it still frequently carries all of the exotic/foreign/inscrutable/mysterious connotations. These connotations happen to coincide with many of the stereotypes held of Asian Americans. Furthermore, by definition, the word "Oriental" is Eurocentric, referring to things east of Europe. For these reasons, some Asian American activist types decided that "Oriental" was a Bad Word, and that "Asian" was more accurate, less Eurocentric, and less loaded with strange connotations. No big deal, right?

Well, a lot of people didn't want to change their language usage. Some people grew up using "Oriental" and saw nothing wrong with the word. Others came from other parts of the world, where hip-activist-American-English-linguistic-evolution hadn't hit. Still others never encountered anyone aware of Asian American politics, so had never heard of this word usage change. Some people were exploiting the exotic mysticism connotations and resisted change. (Very early on, you would see articles about business and trade in Asia, whereas the travel articles would talk about visiting the Exotic Mysterious Orient.) Finally, some people were convinced that this was a typical case of left-wing-politically-correct-thought-police-mind-control (which it was) and decided in typical right-wing-politically-correct-knee-jerk-response that the word usage change was intrinsically evil and had to be resisted at all costs.

For a while, therefore, you could identify a person as being an American who was aware of and sympathetic to Asian American politics by his/her word choice. Now, however, many exploitation-types have realized that saying "Asian" instead of "Oriental" is the cool thing to do, without changing any of their stereotypes and misconceptions. (You can force a person to change his/her behavior, but you can't force a change in thought.)

The upshot is to use whatever word you feel most comfortable with, or that makes your listeners most comfortable, but don't be surprised if someone takes offense. And in the time you save by not worrying about word-usage, try to make the world a better place.
