Yes. This is how they avoid saying the word, "muslim" -- by lumping Indians, Chinese, Pakistanis, etal into the same overly broad category -- sort of like Clinton firing all US attorneys when all he really wanted to do was fire the ones investigating him in Arkansas. I'd bet the farm that the group the writer refers to are all muslim.
No they don't. Chinese are "Orientals", a word the United States is too PC to use.
