Psychologist Kelly Brownell:
"These kind of messages are toxic. They pressure people, especially girls, to be at odds with their bodies and to fight against whatever natural weight they might have. They force into the public psyche an arbitrary and unrealistic ideal that is attainable by few and leaves a great many scars in its wake."
"[Lawrence's] male co-stars look even healthier (and have some seriously big muscles) yet no one thinks they are too healthy or big boned or big boobed or just plain old fat."
Many of us have trouble with accepting a powerful female as feminine and/or sexy. Recall the attention to Angelina Jolie's leg at the Oscars? We laugh, because it's absurd.
The physically powerful female (see Lisbeth Salander) disrupts the idea that men are meant to be the burly heroes. It's sending Hollywood folks to their doctors for $10,000 per year HGH prescriptions--and what starts in Hollywood will trickle down.
These attacks on actresses challenge our ability to accept ourselves and each other. We are not showing young girls (or boys) ways of finding or accepting their own intrinsic value. We put celebrities on a pedestal and feel better about ourselves when they crash and burn. We are impressionable and easily controlled by our insecurities (see: the economy), and it's eating away at us. This is how our culture works. But who does it help?
