 For Butler, sex assignment is always in some sense oppressive. Again, this appears to be because of Butler’s general suspicion of classification: sex classification can never be merely descriptive but always has a normative element reflecting evaluative claims of those who are powerful. Conducting a feminist genealogy of the body (or examining why sexed bodies are thought to come naturally as female and male), then, should ground feminist practice (Butler 1993, 28–9). Feminists should examine and uncover ways in which social construction and certain acts that constitute sex shape our understandings of sexed bodies, what kinds of meanings bodies acquire and which practices and illocutionary speech acts ‘make’ our bodies into sexes. Doing so enables feminists to identity how sexed bodies are socially constructed in order to resist such construction.
