Allison Weir sets forth a concept of identity which depends on an acceptance of nonidentity, difference, and connection to others, defined as a capacity to participate in a social world. Weir argues that the equation of identity with repression and domination links "relational feminists" like Nancy Chodorow, who equate self-identity with the repression of connection to others, and poststructuralist feminists like Judith Butler, who view any identity as a repression of nonidentity or difference. Weir traces this conception of identity as domination back to Simone de Beauvoir's theories of the relation of self and other.
