What do immigration raids and police brutality have in common? They’ve both sparked growing social movements demanding justice. Those linkages are examined in the new book, “When We Fight, We Win!: Twenty-First Century Social Movements and the Activists That Are Transforming Our World.” The book looks at movements ranging from immigration to Black Lives Matter, to the Fight for 15, to LGBTQ rights. We speak with the book’s author, education activist Greg Jobin-Leeds; the book’s art director Deymirie Hernández; and two of the activists featured in the book—Jitu Brown, national director of the Justice Alliance in Chicago, and Isabel Sousa-Rodriguez, Ph.D. student at the CUNY Graduate Center and immigration activist.
