In this volume in the Racial Literacy series (6 titles), Osman defines the slippery subject of intersectionality as "the idea that social categorizations like race, class, and gender create interconnected systems of oppression and discrimination." Over three chapters, she explores these constructs ce, gender, and class d how they may or may not come together in intersectionality. As an example of the latter, she cites the abolitionist and women's rights movements, which existed simultaneously but failed to come together in solidarity. As for the former, she offers the example of the Dakota Access Pipeline protest, which brought people together across lines of race, gender, and class. She concludes by discussing how to practice intersectionality in alliance and solidarity. A well-researched, lucid, and insightful exposition of a difficult but timely subject.
