 Tommie Shelby responds to the ambivalence of Appiah and Blum by distinguishing classical black nationalism, which rested upon an organic black identity, with pragmatic black nationalism, based on an instrumental concern with combating antiblack racism (2005, 38–52; 2003, 666–668). Pragmatic nationalism allows Black people to generate solidarity across class or cultural lines, not just through the modus vivendi of shared interests but upon a principled commitment to racial equality and justice (2005, 150–154). As a result, black solidarity is grounded upon a principled response to common oppression, rather than some putative shared identity (2002), thus mitigating the dangers of biological essentialism and tyrannical cultural conformity that Appiah associates with race and racial identities. Anna Stubblefield (2005) provides an alternative defense of Black solidarity by comparing it to familial commitments.
