if gender (and femininity, and masculinity) are intersubjective, then the practice of coming up with a definition doesn't even make sense. the claim that "we know and agree what masculinity and femininity is" is directly contrary to the very obvious statement that such things are intersubjective. the idea of an "incomplete, indeterminate definition" is still notably lacking intersubjectivity, it's still something that you can wield like a truncheon. even if I'll on occasion refer to a femininity or a masculinity, that's very much not the same as trying to define, which is inherently about universalizing.
You're going to have to explain your reasoning here. I know a lot about intersubjectivity, and there's nothing in the literature about how if something is intersubjective you can't define it. If something is intersubjective, that means multiple minds can access it. And of course multiple minds can access a definition. And I have no clue what it means to say a particular definition lacks intersubjectivity. If we can all understand the definition, it's intersubjective.
Intersubjectivity presupposes a common, universally accessible world. Agreement is intersubjective, so I don't see how the claim that we know and agree about gender contradicts gender's intersubjectivity. There may be intersubjective disagreement about gender, but then you'd have to provide an alternative definition. If it's a mistake to define gender altogether, then all the better for Butler and I. Remember it was Padraig who claimed my view was defective because it couldn't give a determinate definition of masculinity and femininity. If we don't need to define these terms then there's no criticism against me, other than your unargued claim that feminine culture does not serve as a real alternative to the patriarchy.
Finally, I have no clue what it means to say that an incomplete indeterminate definition of gender lacks intersubjectivity. When I claim "Communal acceptance determines the behaviors that define a particular gender" that is an indeterminate definition that literally states that gender is intersubjective. That's what the "communal acceptance" part means.
Once again you are trying to critique me using Butler's own claims. Please be more charitable in the future. Judith Butler's arguments are so strong that efforts to criticize her just reiterate her own claims ahahahaha.
