Gilroy's ideological orientation leans towards postmodernism. Postmodernists strongly resist the idea of essential features of social categories, arguing that all social categories are the subject of deliberate human construction and that pathologies in such constructions are the result of oppression and unequal power relationships. The general project is to deconstruct oppressive social categories and reorient them so as to empower the marginalized. Gilroy pursues precisely this project with respect to black subcultures within the nations of the black diasporas. He strongly criticizes any essentialization of black culture and uses the idea of the Black Atlantic to demonstrate the internal fluidity and "hybridity" of the concept of blackness.
