In our society, women are viewed first and foremost as sexual beings, and those who are perceived to be unattractive are frequently mocked. It is true that obese women suffer from widespread derision, but they are hardly alone. Think of the "jokes" about Janet Reno, for example.Pure said:other posters have mentioned health probs, but many of these are for moderate (II) to extreme obesity, which i don't think there's much argument about. i'm sure you, lil slave, agree. but it might to added that 'medical problem' is not a license for ridicule, any more than say, cleft palate (whose odd lisp used to be mocked and called funny) or a woman's loss of her hair (a 'bald lady' was once a figure for amusement).
Women who are marked as too old, too frumpy, too hairy, too heavy, too skinny, too ugly, too trashy, etc. are routinely considered fair game for insults made by individuals and stock caricatures devoid of dignity in TV and film.
There is a thread currently running in the GB called Ugly Women and Seductive AV's. This post is a typical example of a non-obese female being held up for scorn.
