I've noticed this quite a bit in our culture, and also on MN. I need to lose a few lbs and searched a lot of the weightloss threads. There's this prevailing view that if you are thin or very slim it is boasting or 'bragging' to mention it out loud.
One poster said she had lost a lot of weight and was now skinny, then 'apologised' for seeming to boast. No one apologises for admitting they are overweight. (no one should have to either way!)
And in a thread last week or so an OP got insulted and more or less bullied for mentioning she was under 8st at 5'4 and still ate carbs!. What followed was around 5 pages of accusations of eating disorders and snide remarks, and when she attempted to defend herself she was called 'Hangry'.
There definitely is skinny-bashing on here, but I doubt anyone would admit to seeing it. There are also the usual holier than thou attitudes towards fat people, almost patronisingly telling them they must eat too much, even when they confirm that they do not...(not all fat people are secret eaters who venture off on a somnambulist chow down every night in their sleep).
So there is a weird presumption that a slim person must be hungry, joyless and disordered. And that a fat person is secretly gorging.
I am not thin myself! But I notice this stuff a lot. It got me to wondering how, as women, we can't win either way. We feel pressured to keep slim and fit, yet sometimes resent others who have achieved it or had it come naturally for them.
It kind of divides us when we really do need to remain supportive of each other.
I think it says something really odd about our culture when a slim person has to protect themselves on a forum by apologising for it in advance. And in the S&B section I have noticed women over a size 18 are treated much more kindly than those under a size 10. It is too simplistic to call it jealousy, but it does show how uncomfortable so many of us are about weight. And it's no surprise in our crazy world, but i do think it's wise to become aware of it, and check our bias.
