In the face of relentless attacks on antiracist education, a much-needed reckoning with the roots of this latest wave of censorship and an urgent call to action to defend education. In just the last few years, scores of states have introduced or passed legislation that would require teachers to lie to students about structural racism and other forms of oppression. Books have been cut from curricula and pulled from school library shelves. Teachers have been fired and threatened with discipline. As longtime organizer, writer, and high school teacher Jesse Hagopian argues in Teach Truth, what's at stake is the freedom to tell the truth, the ability of students to understand the world they live in, and the preservation of knowledge systems that expose injustice. By exploring the roots and reach of the censorship movement, Hagopian shows how these efforts to suppress truth serve to uphold racial capitalism and silence the histories that threaten entrenched power. Yet the struggle for a liberatory education has a long history in the United States, from the days when it was illegal for Black people to be literate, to the Civil Rights and Black Power movements, to Black Lives Matter at School today. Teachers, students, and their allies are already building a movement - in the classroom, on campus, and in the streets - to defend antiracist education.
