She is one loaded lady!
"The Question of 'the subject' is crucial for politics, and for feminist politics in particular, because juridical subjects are invariably produced through certain exclusionary practices that do not 'show' once the juridical structure of politics has been established"
In this context, Butler is discussing and problematizing this issue of the category of "women" being the subject of feminism. She is saying that this issue of the subject is important to understand because the subject is created by a power structure, in this case juridical. Not only are the subjects produced but they are not declared as such and are therefore normalized by the system. This is problematic for feminism because feminism as it was conceived is an attempt to offer a counter discourse to the current power structures. But we can see clearly that feminism is operating under the same discourse that it is trying to "counter".
This is what I took to be her argument!
