"White feminism" does not mean every white woman, everywhere, who happens to identify as feminist. It also doesn’t mean that every "white feminist" identifies as white. I see "white feminism" as a specific set of single-issue, non-intersectional, superficial feminist practices. It is the feminism we understand as mainstream; the feminism obsessed with body hair, and high heels and makeup, and changing your married name. It is the feminism you probably first learned. "White feminism" is the feminism that doesn’t understand western privilege, or cultural context. It is the feminism that doesn’t consider race as a factor in the struggle for equality.
White feminism is a set of beliefs that allows for the exclusion of issues that specifically affect women of colour. It is “one size-fits all” feminism, where middle class white women are the mould that others must fit. It is a method of practicing feminism, not an indictment of every individual white feminist, everywhere, always.
