Some critics have accused Butler of elitism due to their difficult prose style, while others claim that Butler reduces gender to "discourse" or promotes a form of gender voluntarism. Susan Bordo, for example, has argued that Butler reduces gender to language and has contended that the body is a major part of gender, in opposition to Butler's conception of gender as performative. A particularly vocal critic has been feminist Martha Nussbaum, who has argued that Butler misreads J. L. Austin's idea of performative utterance, makes erroneous legal claims, forecloses an essential site of resistance by repudiating pre-cultural agency, and provides no "normative theory of social justice and human dignity." Finally, Nancy Fraser's critique of Butler was part of a famous exchange between the two theorists. Fraser has suggested that Butler's focus on performativity distances them from "everyday ways of talking and thinking about ourselves. ... Why should we use such a self-distancing idiom?"
