Citing W. E. B. Du Bois’s 1903 observation that the ‘colour line’ is the defining characteristic of American society, she writes that ‘Unless white people learn to acknowledge, rather than deny, how whites are complicit in racism, and until white people develop an awareness that critically questions the frames of truth and conceptions of the “good” through which they understand their social world, Du Bois’s insight will continue to ring true.’
