Feminist writer and critic Jessica Valenti had a really nice take-down of this ridiculous trend in yesterday's Guardian:
You know what is going to help women achieve equality with men? Creating policies that promote gender equality and don't punish women for being the ones who bear children; stopping sexual predation; and changing a culture that is rife with large and small instances of misogyny and sexism.
In support of that last goal, all of those incredibly privileged women writing those books should take a lesson from the young actress Emma Stone, who had the presence of mind and the guts to publicly call out sexism when she saw it - from her boyfriend, no less - and did it in a way that allowed him to learn from his error, rather than get defensive about it.
This is what feminism looks like.
