So is this a case of "non-white privilege"?
There have been a few studies on why people take to someone foreign, indicating a clear underlying racist/sexist stereotype. One for example:

Compared with the White stereotype, the Asian stereotype was more feminine, whereas the Black stereotype was more masculine. Study 3 found that heterosexual White men had a romantic preference for Asians over Blacks and that heterosexual White women had a romantic preference for Blacks over Asians; preferences for masculinity versus femininity mediated participants’ attraction to Blacks relative to Asians.
