That's why I cited a source:
"While a number of reference works used in the United States describe Oriental as pejorative, antiquated or offensive in some instances, the American Heritage Book of English Usage notes that
It is worth remembering, though, that Oriental is an ethnic slur to be avoided in all situations. It is most objectionable in contemporary contexts and when used as a noun, as in "the appointment of an Oriental to head the commission". In these cases Asian (or a more specific term such as Vietnamese, Korean, or Asian American, if appropriate) is the only acceptable term. But in certain historical contexts, or when its exotic connotations are integral to the topic, Oriental remains a useful term.[3]"
It's a grey area, but why would you even want to risk it when other non-offensive and more accurate words are readily available?
