NO, for the bazillionth time in the last hour, NO. Oriental is something that comes from the Far East. Not all of Asia is in the Far East, so it is impossible for Oriental to = Asia. PERIOD.
Oriental is typically used for objects, not people, so that is why people get offended.
And according to the wiktionary, "One complaint has been its frequent use by some to denigrate Asian people and people of Asian descent, which many feel has given the word itself a bad connotation. Others object to the term being used as a blanket term for people of Asian or East Asian descent, since that ignores the varied and often disparate cultures and histories of that area, thus emphasizing the sameness or indistinguishability of those cultures and peoples (and in reverse, imputing on the user a lack of awareness and concern for the cultural difference within Asia). A third reason given is that the term is so vague that it is never clear which countries are included within the term. Most users, however, do not employ the term with any malicious intent whatsoever, and view it as a convenient and innocent generic term in the absence of more precise information, equivalent to the frequent use of the term westerner in Asia"
