Given their track record, I wonder how the primitive knew the family was of Japanese derivation.
Over the years, there's been plenty of primitive comments on one thread or another where the primitives mixed up the Japanese with Chinese, Korean, Vietnamese, Laotian, Cambodian, and so help me, Filipinos, which betrays that the primitives can't tell the differences in the nationalities of the Far East.
As far as the primitives seem to know, everybody's white, yellow, brown, or black, with no distinctions within those colors.
