An interesting blog post from ProfessorWhatIf examining the dividing line on white racial identity.
Yet, despite what sicko groups like WAR (white Aryan resistance) would have us believe, there is no such thing as racial identity outside of the social construction of race. This is why who counts as white has changed (and continues to change) over time. Irish, Jewish, Italian, and Eastern Europeans with light/white skin have at various historical periods not been considered white. The changing rules and requirements regarding who gets to be in the white club are related to systems of power and privilege. This is why whiteness is defined by exclusion rather than inclusion.
By preventing various ‘Others’ from being construed as white, white privilege translates into better jobs, better treatment, better legal protection, and on and on. Whiteness functions as a system that confers entitlement, power, and privilege on some, and oppression, disenfranchisement, and lack of power on others. Thus, racial oppression is the key reason behind the construct of the white race and, as Judy Helfand writes in her piece “Constructing Whiteness,” this translates into white people benefiting “disproportionally from the race and class hierarchy maintained by whiteness.”
