While looking through my blog's stats, I noted a number of links coming from Sociological Images. Specifically, from a post where the author considers the "benefits" of being fat. As you might suspect, this is not actually the conversation the author is having, but rather it is an example of the kind of "this must be why you're so fat" line of thinking that has come up so often in the #thingsfatpeoplearetold. I replied with a comment, but I wanted to include it here as well...
I'm afraid your evidence does not seem to support your conclusion. As the #thingsfatpeoplearetold meme demonstrates, fat people are told all manner of things and given the existing social structure, many fat people feel an obligation to be credulous. The lesbian quoted did not independently think she gained weight to distance herself from male attraction, but rather was told to think that. Even in that context, it is not a suggestion of an active instigation, but rather a psychological explanation. The fact that we feel the need to psychologically explain the existence of fat people, though, is far more telling. It is an effort for privileged persons to rationalize the existence of an underprivileged group. This very act is one not of understanding, but of enforcement of stigmatization. Fat people are told something must be blamed for our presence. This is never an act of respect. It does not matter of blame is laid on ourselves for perceived immoralities, on psychological desires rooted in formalizing our disempowerment, or corporate conspiracies to deprive us of exalted thinness.
The Postsecret post is, at least, in the actual voice of a fat person, but it still doesn't tell us anything about why she came to be fat and it is still a reflection of all too common clichés that fat people are told. The writer has learned to hold herself responsible for her body. She has been told to explain her body, to rationalize it. She presumes that she could be thin because she has been told this is the only allowed presumption a fat person can have. She frames her attempted justification not on why she is fat, but why she is not thin. THIS is what fat people are told to answer for just as much as "why are you so fat". It presumes that weight loss, which fails 95% of the time, is still expected of us and any failure to lose weight is the sole responsibility of the fat person. She is not expressing an answer as to why she was fat in the first place, though. Rather, she is trying to answer for her continued fatness. The truth, though, is that she is not afraid to lose weight. She may be afraid that weight loss won't solve her problems (it won't), but she is not afraid to lose weight. She wants it desperately. She, like so many fat people, has been made to feel personally responsible for the fact that her weight loss efforts have not succeeded. Like many others, she has apologetically concluded "she doesn't want it bad enough".
This isn't about benefits of fatness. These are illustrations of the shame and stigmatization imposed on fat people.
