“Intersectionality […] is often reduced, in common understanding, to a due consideration of the various axes of oppression and privilege: race, class, sexuality, disability, and so on. […] The central insight of intersectionality is that any liberation movement — feminism, anti-racism, the labor movement — that focuses only on what all members of the relevant group (women, people of color, the working class) have in common is a movement that will best serve those members of the group who are least oppressed.”
