How do "whiteness" studies challenge racism?

As sociologists,we need to understand that whiteness affords structural advantage.Those engaged in white studies endeavour to reveal the social underpinnings of whiteness with the goal of challenging its privileged status.Race is often thought of as a colour-as being non-white.The prevailing approach to whiteness is that it is colourless,that whites are simply members of the human race.Within such an approach,disturbing dualisms emerge in which whites are thought of as simply people while non-whites are understood as distinct races.
Whiteness carries with it privilege;in countries such as the United States,Germany,England,and Denmark (among others),whites are plainly visible,often occupying front-line positions (managers,doctors,servers,concierge),while non-whites are often out of sight (kitchen staff,janitors,housekeepers).
