Well, you'd be surprised what some feminists actually believe. That said, it is not necessrily a matter of biological facts like men have a penis and women have a vagina, but also the social and cultural context in which it is viewed.
If you want a actual quote from Butler here you are:
If the immutable character of sex is contested, perhaps this construct called ‘sex’ is as culturally constructed as gender; indeed, perhaps it was always already gender, with the consequence that the distinction between sex and gender turns out to be no distinction at all.(Butler 1999, 10–11)
That's what I'm talking about though. I've found that quote by Butler as well, but don't understand it to mean that genitals exists in our heads before they're formed in corporeal reality or whatever. Well, in some way they do, but this doesn't cause them to become real.
She's, as far as I can tell, addressing the line feminists had drawn between sex and gender to push back against biological determinism.
Helpful link though.
3.3 Are sex and gender distinct?
In addition to arguing against identity politics and for gender performativity, Butler holds that distinguishing biological sex from social gender is unintelligible. For her, both are socially constructed:
If the immutable character of sex is contested, perhaps this construct called ‘sex’ is as culturally constructed as gender; indeed, perhaps it was always already gender, with the consequence that the distinction between sex and gender turns out to be no distinction at all. (Butler 1999, 10–11)
(Butler is not alone in claiming that there are no tenable distinctions between nature/culture, biology/construction and sex/gender. See also: Antony 1998; Gatens 1996; Grosz 1994; Prokhovnik 1999.) Butler makes two different claims in the passage cited: that sex is a social construction, and that sex is gender. To unpack her view, consider the two claims in turn. First, the idea that sex is a social construct, for Butler, boils down to the view that our sexed bodies are also performative and, so, they have “no ontological status apart from the various acts which constitute [their] reality” (1999, 173). Prima facie, this implausibly implies that female and male bodies do not have independent existence and that if gendering activities ceased, so would physical bodies. This is not Butler's claim; rather, her position is that bodies viewed as the material foundations on which gender is constructed, are themselves constructed as if they provide such material foundations (Butler 1993). Cultural conceptions about gender figure in “the very apparatus of production whereby sexes themselves are established” (Butler 1999, 11).
[...]
And this is what Butler means in saying that physical bodies never exist outside cultural and social meanings, and that sex is as socially constructed as gender. She does not deny that physical bodies exist. But, she takes our understanding of this existence to be a product of social conditioning: social conditioning makes the existence of physical bodies intelligible to us by discursively constructing sexed bodies through certain constitutive acts. (For a helpful introduction to Butler's views, see Salih 2002.)
Clears up one thing for me at least, but I still don't understand her position.
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).
I take solace in the fact that the pros are unclear on this as well.

If she means this sort of thing:
Many people, including many feminists, have ordinarily taken sex ascriptions to be solely a matter of biology with no social or cultural dimension. It is commonplace to think that there are only two sexes and that biological sex classifications are utterly unproblematic. By contrast, some feminists have argued that sex classifications are not unproblematic and that they are not solely a matter of biology. In order to make sense of this, it is helpful to distinguish object- and idea-construction (see Haslanger 2003b for more): social forces can be said to construct certain kinds of objects (e.g. sexed bodies or gendered individuals) and certain kinds of ideas (e.g. sex or gender concepts). First, take the object-construction of sexed bodies. Secondary sex characteristics, or the physiological and biological features commonly associated with males and females, are affected by social practices. In some societies, females' lower social status has meant that they have been fed less and so, the lack of nutrition has had the effect of making them smaller in size (Jaggar 1983, 37). Uniformity in muscular shape, size and strength within sex categories is not caused entirely by biological factors, but depends heavily on exercise opportunities: if males and females were allowed the same exercise opportunities and equal encouragement to exercise, it is thought that bodily dimorphism would diminish (Fausto-Sterling 1993a, 218). A number of medical phenomena involving bones (like osteoporosis) have social causes directly related to expectations about gender, women's diet and their exercise opportunities (Fausto-Sterling 2005). These examples suggest that physiological features thought to be sex-specific traits not affected by social and cultural factors are, after all, to some extent products of social conditioning. Social conditioning, then, shapes our biology.
Then, OK. Reasonable. But I'm not sure she does.
What I'm gathering from all this is that I need to put in a lot more work than I'm willing. Anybody here know about this well enough to spoonfeed it to me?
