>her philosophy often was more descriptive and and deconstructionist

Yeah that's roughly my understanding as well. I don't really remember Butler saying anything along the lines of "you should all act your gender like this!", though there is a kind of prescriptivism at the heart of any descriptive enterprise (i.e., what I'm describing is true and should be seen as such, or something like this).

>About how we can look individuals that don’t act in the binary and try understand their gender role

Not only that, but also about how to understand oneself when one is unable to identify with some such classification. It really is a work that moves in the direction of some limited kind of liberation.
