I am reminded of a South African court case I read a while back (which I can't seem to find now) where there was some confusion when a Japanese man was thought to be Chinese. Chinese people were not considered "white" but Japanese people were. If I remember correctly, he was trying to board a bus (or a taxi?) and was denied because of Apartheid laws but was later able to "prove" his "whiteness" by showing he was Japanese. Humans suck at recognizing the human-ness of other humans.
