Feminism is about choice, and the ability for women and men to make choices equally..
Feminism isn't about choice. It occupies some of the most bitterly contested political ground, and it's often fiercely combative within and amongst its own factions. Where its various strands do agree is that's about levelling a playing field that's been skewed against women since the year dot by a society in which every single strata is systemically, institutionally and socially set up to benefit men. It's about redressing discrimination against women, and preserving our hard fought-for sex-based rights to enable protection from violence at the hands of the physically stronger sex (a problem which is still, sadly, all-too pervasive).
In a society like that, these are factors which may well determine the choices we make: in every way from the pay gap between the sexes to maternity legislation to the 'glass ceiling' often experienced by female professionals.
If those injustices are redressed and free choice later happens as a natural consequence, all to the good. But choice alone has never been the real objective of feminism.
