The term “whiteness” has at least two different meanings, which should not be confused with each other. One meaning of “whiteness” refers to the contingent social construct of whiteness; the other refers to the necessary social construct of whiteness. Whiteness (contingent social construct)—which can also be called and understood as whiteness (current social construct) for practical purposes—exists and is foundational to racism. However, there is no such thing as whiteness (necessary social construct). The social construct of whiteness is not necessary for society to exist. Whiteness is not a necessary truth; it is a merely a contingent truth. Race currently exists as a social construct, but it does not have to exist as a social construct.
(Obviously, racial color blindness and avoiding racial categorization does nothing to challenge the social construct of race, as it merely allows people unaffected by racism to deny that there is a problem. In addition, although the statement “race is not the problem, racism is” is true, this statement is still made within the narrative that only people of colour are raced or racialized, which is still another contingent truth. A better articulation that emphasizes the unnecessary racialization of people of colour over the idea that racializing people of colour is necessary would be: “racialized people are not the problem; racialization is.”)
