I believe that Lebesco's statements are similar to butler's in regards to the idea that language speaks to the realities and artificialities of truths we think we know. I believe that she was saying that the artificiality pertains to the fact that language is interpreted by people differently. So the term queer and fat can be understood differently by different people. As in the movie Female Trouble, we can see that Dawn and the Dashers become obsessed with her beauty. This movie is not a typical hollywood portrayal of what is beautiful, which is one thing that I kept noticing throughout the film. I also found it odd that they thought she was so beautiful after getting acid all over her face. I say that because to the average person, having acid sprayed all over one's face would make them feel less beautiful. So, Dawn portrays this image of beauty and challenges the language of what it means to be "fat", and "desirable". This pertains to the idea of size, sexuality and desire as talked about by Butler.
Butler says the term queer derives links to "accusation, pathologization, and insult". This is similar to the term "fat" because in society, "fat" has negative connotations and often can be used as insult. I agree with Lebesco's comment that its potential subject for rejecting normative regimes of beauty. This movie challenges the idea of beaufitul and makes it apparent that the skinny, caucasian, pretty girl isnt always the desirable trait.
Language is used as a tool, not as a set in stone idea in this regard.
Overall I liked the movie's take on what we see as beautiful and the way that they challenged many ideas of society's idea of "normal" and "fat".
