If you are referring to my comments, please note that I was just responding to a question. Racial prejudice is alive and thriving in asian minority groups. Calling any asian a wrong nationality, is just not a nice thing to do and should be avoided. Dr. Dao was also referred to as a "chinaman" in this thread. The word is considered a derogatory term.
From Wickipedia: The term Chinaman is described as being offensive in most modern dictionaries and studies of usage.[23] It is not, however, as offensive as chink.[24] The New Fowler's Modern English Usage considers Chinaman to have a "derogatory edge",[25] The Cambridge Guide to English Usage describes it as having "derogatory overtones",[24] and Philip Herbst's reference work The Color of Words notes that it may be "taken as patronizing".[26]
