I'm glad this author tackled this as it's a vastly understudied subject - fat studies is really still trying to find its feet, and the juxtaposition of that lived experience with the experience of gayness and masculinity is doubly underexposed. However, as someone who shares the titular identity categories, I didn't feel in any way represented by this text. I'd never heard of the organizations and conferences referenced - perhaps this is a generational divide between an older, more ghettoized pre-internet queer community and that of today. This book's scope, in being limited to just those demographics, was underwhelming and distinctly alienating for me.
I also didn't like that the author uncritically accepted everything these men told him about their experiences. Of course I can vouch for the unique stigmatization of being fat within the gay community. However, the author took no efforts to recognize the privileges held by this class, in their overwhelming whiteness, (in the case of the convention-goers) upper class status, and, obviously, maleness. My experiences with the "chub" and "bear" communities reveal them to be a hotbed of anti-feminine misogyny and paradoxically, body-shaming. Some of that comes through in quotes used in this book, but it is neither challenged nor examined. The victimization narratives presented here are accepted in totality, with no consideration of the privileges that contribute to its construction.
I liked the author's use of theory, although it seemed to be a bit of a crutch at times, grasping at straws to connect experiences with Goffman and Sontag. However, the theoretical research was thorough and well done.
Overall, I think a lot of the book's failures can be attributed to the methodology - I would imagine it is difficult to take a critical approach to ethnography without alienating the author from the people he's studying. However, that does not excuse justifying and excusing the ways in which prejudice informs their identities. In all, this is a good starting point for the author, or perhaps someone else, to write a more exhaustive and inclusive study of the intersections of fatness and queer identity.
