This is about a MUCH larger picture...
Honey, it ain't stupid. Exactly who did you listen to when you were a teen on the subject of "cool", your parents? I doubt it VERY much... or just maybe what all of your friends and/or cool people on TV were wearing/doing/saying? Is it just BRAVO, nope. On the other hand, when a show with this kind of ratings just plays the same tired "Size 6 is fat disgusting and saftig" rap, it's disappointing. Any time there's an opportunity to make a move toward positive change, and it's not taken, it's disappointing.
If people continue with this stupid 'what will teenage girls think?' mentality perhaps it should be reminded that it is the parents responsibility to inform their kids about how the world works, how this is TV and not real, and guess what, people do talk about other people's weight, appearance, etc. It is not BRAVOTV's responsibility.
Television is ubiquitous, it's visual, it's aural, it's on in some homes (and a lot of kids' bedrooms) 24/7. This latest generation were raised with a CONSTANT bombardment of marketing images. There is truly nothing more pervasive or more seductive in shaping our attitudes. Do parents have a responsibility to explain the difference between "reality television" and reality? Sure. But I'm guessing most are just changing the channel...
P.S. Ever see Fahrenheit 451?
