There are aspects of traditional femininity, from home-making to empathy, that should belong to men too. If we move away from biological determinism we enter a world with more freedom, not less, because then those behaviours traditionally associated with masculinity and femininity could become real choices for each individual.

To repeat some of the most basic facts: women still do not have the equal political power they have long sought, since only one in five MPs is a woman. They do not have economic equality, since the pay gap is still not only large but actually widening. They do not have the freedom from violence they have sought, and with the conviction rate in rape cases standing at just 6 percent, they know that rapists enjoy an effective impunity in our society.

While girls have always been encouraged to see self-decoration as a central part of their lives, today they are also exposed to a deluge of messages, even at an early age, about the importance of becoming sexually attractive. These dolls are just a fragment of a much wider culture in which young women are encouraged to see their sexual allure as their primary passport to success. This highly sexualised culture is often positively celebrated as a sign of women's liberation and empowerment.

The rise of a hypersexual culture is not proof that we have reached full equality; rather, it has reflected and exaggerated the deeper imbalances of power in our society. Without thoroughgoing economic and political change, what we see when we look around us is not the equality we once sought; it is a stalled revolution.

In the US where the girls are doing not as well as boys in some tests, the information seems to be interpreted as showing that girls just aren't as good at these things so we can't expect them to be mathematicians. But here in the UK people are reacting to boys not doing as well as girls in maths exams by saying, what can we do about that, we need to fix that ... This difference is telling.

Somehow the ideals of sexual liberation had become twisted until women were being told that if they didn't buy into an increasingly narrow image of what female sexiness looked like, then they must be prudes.No matter if they were looking for something freer rather than less free, nobody wants to be told they're frigid. So even though this wasn't about disliking sex, but disliking sexism, the label 'prude' had become an effective gag on dissent.

We cannot pretend that this is all about women as victims, when many women are deeply complicit in creating and selling this culture.

The ease with which prostitution is presented as an acceptable choice for women dismisses the psychological trauma that actually seems to be not the occasional, but the inevitable, result of selling sex.

The imperative is to better oneself not through any intellectual or emotional growth, but through physical remaking. Such media encourage young girls to believe that good looks rather than good works are at the centre of the good life. What makes these messages particularly attractive to young women is that they constantly return to the language of empowerment and opportunity.
