What we need is a tough new kind of feminism with no illusions. Women do not change institutions simply by assimilating into them. We need a feminism that teaches a woman to say no - not just to the date rapist or overly insistent boyfriend but, when necessary, to the military or corporate hierarchy within which she finds herself. We need a kind of feminism that aims not just to assimilate into the institutions that men have created over the centuries, but to infiltrate and subvert them.
