The article When Difference Becomes Dangerous analyzes how intersectional identities are formed and how whiteness functions as a protective cover in William Faulkner’s novel Light in August. It explores the ways racial difference and the threat of miscegenation are depicted in the Southern United States, and how social constructions of race affect characters’ identities and social status. The author argues that whiteness provides privilege and protection, while anyone who exists outside of that social definition faces danger and instability. Through Light in August, Faulkner illustrates how racial ambiguity and societal fear of racial mixing reinforce systems of white supremacy and social control.
