Educational leadership serves a pivotal function in establishing the tenor of campus cultures. Executive decisions shape educational policy and practice in ways that either hinder or advance marginalised students' academic success. Leaders are in powerful positions to modify unjust academic ecosystems and to de-ideologise the white-centric dominant ideologies that lead to student pushout. Leadership actions tend to justify the status quo rather than to deconstruct campus culture and reconstruct antiracist options. Inaction from leadership has resulted in cultural discontinuities that lead some students to self-deidentify from academia. This article expands upon "cultural mismatch theory" to describe how race dysconsciousness, academic capitalism and rugged individualism operate to buttress ecosystemic conditions that create racially-antagonistic campus cultures. We propose strategies that leaders can implement to eradicate dominant ideologies at their home institutions and within educator-student relationships and individual mindsets. We also discuss important considerations and corresponding actions for creating culturally-congruent equity-focused educational spaces.
