STOCKTON — Anna Malaika Nti-Asare glided easily around her ninth-grade classroom last week teaching a 90-minute college-level ethnic-studies lesson to 33 students merely a decade younger than she is.

“Sexism, class oppression, gender identification and racism are inextricably bound together,” the 24-year-old Nti-Asare told her students as she discussed black feminist theory.

“I’m not only a woman. I’m a black woman. You can’t pull people’s identities apart. They have to go together. Black feminism says if you care about liberating people, you have to care across the board. You can’t pick or choose.”
