 It also requires caution with respect to the types of identifications one makes. For Hale, identification as a member of a category involves both identifications with members of that group as well as identifications as not-members of some other category (119). There may be pressure, through uptake of the category ftm, for example, to identify primarily with non-trans men and to dis-identify with butch lesbians. Such pressure, for Hale must be avoided (119). Identification with may operate independently of identification as a member of category (on the basis of, for example, historical ties). The making of such identifications must be guided by the exercise of moral and political agency. In light of this, Hale argues, gendered self-identities must be made secondary to moral and political identifications (120).
