Nok:
How bout this instead?
Still binary, true, but that was kind of the point - not to claim that all women fall into one of those two categories, but to make the point of the dichotomy for the sake of illustrating the illogic of societal distaste with fat. Not sure how to do that elseways.
Anyway, tried to redress the more intense phrasing - coming off as misogynistic myself was furthest from my intention. Inflammatory, certainly, but not towards women, more towards people that design our fashions and even in the largest try to hide fat as if it is a sin, wrapping it in loose cloth to slim and obscure, while the other side of the industry does everything it can to reveal. It's just... weird.
Anyway, so again, I'm sorry to have offended you.
The Larger Side - A Rant on the Irony and Hypocrisy of Fetishizing Thinness while Tabooing Fat Admiration
(Note: This was pure opinion, and reactionary, with a goal halfway between conversation and being pointed.)
Being into fat women isn't a fetish.
Being into thin women is a fetish.
For millions of years, a fat female body has meant fertility, which, let's face it, is the core of sexuality every bit as much as fun is.
A thin female body, on the other hand, has no biological reason to be attractive (I am not trying to be offensive here, I am talking about the biological purpose of physical attraction): it doesn't as prominently display the nutrition necessary to make baby brains, it doesn't feel as good in bed, and, for most thin women, it also kind of sucks to inhabit... except, debatably, for the attention it gets from people that fetishize thinness.
And that's the crux of the problem: two of the most common reasons to strive to be thin are: one, for that, frankly, biologically-illogical attention, and then the only reason for that attention is a novel and deviant modern cultural norm based largely around just how difficult and unnatural it is to be thin; and two, to avoid the negative social attention heaped on anyone that doesn't laud the cult of thinness or has the audacity to actually show in public a body that is larger than borderline anorexic.
It's even become adopted by the medical community itself, despite the dearth of actual evidence. Does excessive visceral abdominal fat have a correlation with some diseases? Yes, yes it does, and that's probably one of the reasons the waist-to-hip ratio is also relevant to instinctual physical attraction to a woman's body.
But there's grosse fallacies imbedded in the medical fear of fat, most prominently: that most fat is not unhealthy; that exercise and healthy foods have far more impact on health than body weight does; and, OF INCREDIBLE IMPORTANCE, that the disease and damage (physical, psychological, social, etc.) caused to individuals and society over the last several decades of cultural bodysize dismorphia and the pursuit (read: fetishization) of female thinness, despite it being neither natural nor healthy, is probably LITERALLY INCALCULABLE (but, certainly, absurdly, obscenely, disgustingly, despicably vast).
I have a background in debate and public speaking, and I studied human biology, psychology, and sociology in college. Your argument is flawed. If you wish to critique the societal concepts of beauty, doing it through a biological lens makes no sense.
Biological attractiveness is about which traits best encourage reproduction. This isn't a static feature. The basic concept of evolution necessitates this fluidity.
In addition, human attractiveness is best understood through sociology and psychology rather than biology. Since humans are very good at transforming our environment to suit our needs, our drive to reproduce is based on other factors (e.g. culture and personal taste).
I find your so-called rant utterly fascinating. You claim that this is a critique of society, but you also clearly indicate a right way and a wrong way to be attractive as a woman. You say things like "A thin female body, on the other hand, has no biological reason to be attractive" and call the desire to be thin "neither natural nor healthy".
By your logic, thin women should either not exist or not be considered attractive by the larger society. This isn't a critique of social beauty so much as it is a long-winded way to body shame. It is both misogynistic and ablest.
