For what purpose does Oluo allude to the poet Walt Whitman in Chapter 16: I Just Got Called Racist, What Do I Do Now?

Oluo is explaining near the end of the chapter how “if you are white in a white supremacist society, you are racist. If you are male in a patriarchy, you are sexist. If you are able-bodied, you are ableist” (164). To make this idea more palatable to those who may find it too extreme, she likens the idea to the way in which within one day, a person can be generous, stingy, mean, and kind. She characterizes this idea as not being very unusual, since after all, we do “contain multitudes,” (164) just like Walt Whitman wrote in his volume of poetry called Leaves of Grass.
