Naked Old Ladies

Women in the third world get naked as an extreme way to say they'r opressed. I am a woman and I come from the third world, but this whole thing appears to me as a bad joke. I find it effectist and cheap. Last month, eleven 50 year older women made a 2007 calendar: that was ther attempt to achieve freedom. But that seems a huge contradiction. They do what they attack. It's like being against North America wearing a Nike T-shirt.
I will post one of their pictures as soon as I can, so you can take a look at that crap and be able to judge by yourselves. Aren't there more "civilized" ways to fight sexism?
