 More recently, Amar Acheraiou in "Questioning Hybridity, Postcolonialism and Globalization" challenges Bhabha's theory of hybridity on theoretical as well as ideological and historical grounds.He criticizes Bhabha for examining hybridity from a narrow, "synchronic" perspective confined to the 19th century, instead of adopting a "diachronic" view which renders better this concept's historical depth.He also reproaches this theorist for stripping the notion of hybridity off its constitutive racial connotations and considers this as an essentialist gesture.
