Thanks for the share. I too went through the whole girl power I'm totally empowered by dressing slutty and being promiscuous. It was fine, I had fun but I certainly didn't end sexism by doing it.
I've just finished Hags by Victoria Smith, it's an excellent book. She talks about the cyclical nature of feminism; how the next generation always want to start again, forget the older women who went before.
In part I think it's to do with hormones, you know when you're young and virile you want to own that, feel empowered by feeling sexy. It's not till you've had kids that you think 'hang about, what happened to equality?!
