Feminism really turns into something very different depending on what your basic definition might be, even if you are unaware of that basic definition. If you start from the ideal of equal treatment for men and women you get one set of conclusions. If you start from the ideal of supporting women you get a different set of conclusions. Sometimes. Not always.
As several of her commenters noted, supporting women as an end-goal can lead you into some pretty strange and hard-to-defend positions. If you follow the theoretical argument, you end up defending the right of an individual women to make, well, stupid decisions. For me, the key is the the word individual. I can support women in general while acknowledging that an individual woman may not always be deserving of support in doing what she wants to do.
Or…am I falling into a trap whereby I am setting myself up as the superior woman, and others as…lesser?
