 However, given what was said above, it is far from obvious what we should make of Butler’s claim that sex “was always already gender” (1999, 11). Stone (2007) takes this to mean that sex is gender but goes on to question it arguing that the social construction of both sex and gender does not make sex identical to gender. According to Stone, it would be more accurate for Butler to say that claims about sex imply gender norms. That is, many claims about sex traits (like ‘females are physically weaker than males’) actually carry implications about how women and men are expected to behave. To some extent the claim describes certain facts. But, it also implies that females are not expected to do much heavy lifting and that they would probably not be good at it. So, claims about sex are not identical to claims about gender; rather, they imply claims about gender norms (Stone 2007, 70).
