Why do women hate their bodies

Although I had a perfectly ordinary normal childhood I never came across this concept of women hating their bodies until I was in my 30s. I had never heard anyone talk about this and I am not sure I have heard many women talk about it since, just read about it.

I find it completely incomprehensible. Walk around the streets you can see people of all shapes and sizes and all levels of looks. How many of them have perfect figures in every way or perfect faces. None that I know of. Yet they are wandering around in family groups with matchingly ordinary men or with friends or on their own and no-one is reeling with horror at the sight of any of them.

I know my figure isn't perfect, great big navvy's hands - and feet to match. I have never had a waist, my rib cage is on kissing terms with my hip bones. It is in the family, my mother and sister have the same problem. No matter how thin we are the answer to the question 'Does my bum look big in this?' is always yes. As for my face, my lips were (they have thinned down a bit) like two sausages tied at the corners. But it has never bothered me. These are observations not judgments. I also have good eyes, tits and legs, I make the most of my good bits and disguise the worst, but I have never 'hated' my body, not even when I was overweight. I might have wished the excess fat would go, but hate my body or be ashamed of it? what a peculiar idea.
