In this article, we illustrate and address how anti-Blackness and adultism work together in an interlocking form of oppression we call anti-Black adultism. Situated in Amina's (youth author) lived experiences of school, we offer counter-stories that show the ways that educators employed anti-Black adultism to render Amina's civic life incompatible with the academic learning of school and imposed adult-framings of academic success on her as a way to control her in school. We then detail our shared experiences in an affinity group space and youth research project to offer the ways that anti-Black adultism can be disrupted through acts of solidarity. We conclude with lessons for adults to trouble anti-Black adultism to sustain intergenerational work toward racial justice in schools.
