My experience is the same as uhtred. Except I'm tall and thin with a slight frame, which is the ultimate sin to many women. My scars, what I've been through, how I feel, none of those matter because I'm thin & tall so I should count myself lucky. I've been told in a friendly voice by more than one person that they were suprised when they got to know me that I'm not vain or bitchy. Because of course, my personality should be assumed to be vile till proven otherwise based on my physiche. And it's not even the deliberately rude remarks. It's the casual God you're skinny/ I wouldn't have thought you ate that much/ aren't you strong, you look like you'd snap in the breeze/ I have hips/ your legs are smaller than my arms/ you have big boobs for someone so skinny etc etc. Along with all the shit you read and hear everyday about skeletal celebrities, all thin people are starving themselves, bones aren't attractive, real women, prepubescent and so on.
And of course if you ever say no to any offering of food, you are clearly anorexic. Eat loads, and you're bulimic. You aren't allowed esteem or confidence issues, or to have experienced misery or hard times, because you're thin, therefore can't possibly have had anything but a charmed life.
Even the fact I have a lot of lean muscle, and have always been very fit and sporty isn't 'allowed' and invites comments on how suprising it is I'm so strong/fast/agile etc when I look scrawny. And of course i must also be mentally weak and dependent.
None of the assumptions are true, and tbh I figured out a long time a go that they come from their insecurity, misplaced envy, ignorance or general twattishness, that they wouldn't direct at someone bigger because that's something they have empathy with. Skinny women are fair game. And for skinny ideal in the media, there's 100 people in rl, that you meet everyday making snide comments about them.
I do agree that being called fat by passers by is undeniably cunty, but it's just as unacceptable to call someone skeletal. And unlike if an aquaintance said 'my, what great meaty arms you have, you're so fat, just feel the size of them June', when someone says 'my, your wrists are so tiny and bony, you're so skinny, feel this June it's like a twig', society wouldn't agree 'fuck off cunt' is a reasonable response. The same people who happily make skinny digs, are the same people who wouldn't dream of saying to someone bigger 'oh, a salad and exercise? I'd have thought you sat about mainlining pies'. And it's those double standards that annoy me.
