My wife told me just recently that "Orientals" is now a derogatory term and to use the word asian instead. When did this happen? No, she's not PC, but has certain guidelines from her company since she deals with many customers.
The problem is that to appease muslims, the PC crowd has redefined "Asian" to include muslims. To force you to use their meaning the Left is trying to stigmatize the use of the word Oriental—which never had negative connotations. In America "Asian" traditionally meant Chinese or Japanese or Vietnamese, etc. However now you are supposed to include muslims as "Asian".
In has gotten so bad that in England, the code word for Paki or muslim is "Asian". And they never mean Chinese, or Japanese or Vietnamese. They mean filthy religion of hate muslims.
