White Creole racial purity claims fail because cultural immersion itself reads as biological mixing.

Evidence

Nonetheless, the distinguishing principle of racial purity has applied with particular historical force to local Creole whites. Their claims to racial purity have been abnegated through historical insertion into a plantation society tainted by the African presence. Socially exempted from the restrictive practices of white racial purity, white Creoles became free to cohabit, as acceptable social practice, with those located lower down in the color hierarchy. There is, therefore, a connection between cultural and biological creolization. One compromises the purity of the other. Thus, insertion into the bastardized space of Creole culture has biological implications. Cultural immersion (through marriage, conversion, association, style, taste, behavior, etc.) becomes biogenetically transformative. Within the Caribbean context, it has paved the way for sexual relations across racialized boundaries. In turn, the practices of marriage and cohabitation outside of the white grouping serve to reinforce notions of white Creole racial impurity. — David Theo Goldberg, John Solomos, A Companion to Racial and Ethnic Studies, 3195

Categorization

• XREF: Inverts the usual direction of racial logic: here culture contaminates biology, not the reverse; resonates with Lilla Watson-style standpoint inversions and with the Lex Oppia piece on how norms become embodied.
• DEEPTHINKING: The claim that cultural immersion is ‘biogenetically transformative’ reverses the ordinary nature-culture hierarchy in racial thinking — a dense, paradigm-shifting insight about how symbolic pollution becomes read as biological.
