Also, this kind of ventures into the territory of "you can be smart or you can be pretty". It helps perpetrate the idea that you have to make yourself a pariah from the majority of women in order to actually be anything you want to be. That's because the missing bit of information here is that women are as sexist as anyone else and will impose their sense of orthodoxy quite readily.
A genuinely liberated "taking care of business" type of woman may find herself shunned by both the homemaker and the "feminist" crowd.
Both will want to control your choices equally.
That's what this "sexism" rating is all about: feminists want to act like church ladies and impose their neo-victorian attitudes on everyone.
Feminists are Tea Baggers without the biblical references.
