At feministe, the folks are breaking down that dumbass choice rhetoric. Note that just because the Pussycat Dolls chose to dance around singing about women using their sexuality to compete with other women- that doesn't make them feminist. Yes, it's their free choice- but it's not really liberating women in general. It's my free choice to watch Noah's Arc, and fantisize about having hot commitment loving men chasing after me, but nobody is freer because of that action, you see?
Also, campus sex magazines are predictably stupid. Not related to feministe, why don't we have a law against this? I got androgyne on this funny quiz.
