Dennis Prager wrote on interesting article on the continuing trend of women exposing their bodies. He believes it is the promotion of the ideal that mean and women are the same.
He concludes that women are saying: "I am a woman. And I will declare it in one of the only ways left to me -- I will show you my female body."
My thought is what happens when even that is taken away. After Janet Jackson revealed her breast on national TV, some people tried to defend it by saying "What's the big deal. It's only a boob." In essence, they are saying that breasts are no longer sexual, and by extension, not definitively feminine.
Thankfully, most men don't agree. If it was "just a boob" it would not have been the most "Tivo'ed" moment to date.
