The dominant use of the word ‘Caucasian’ instead of ‘white’ effectively hides
color behind a wall of pseudo-science. Despite a history of scientific
falsification, ‘Caucasian’ was adopted into American vernacular in the
mid-twentieth century as a means of reconsolidating whiteness as a biologically
distinct category of people (Jacobson 1998). (Reitman, 2006, p. 272)
In truth, the act of using ‘white’ only reveals to whites their own
privilege, the historical politics of whiteness. (Reitman, 2006, p. 273)
In other words, using the term "white," instead of the scientifically inaccurate "Caucasian," strips away this notion that "white" is normal or default or neutral and that people of color are inherently deviants of this construction of normalcy.
