All this arguing over the meaning of feminism and who is and who isn't a feminist has made one thing clear to me -- the fact that we can have these kinds of arguments means that the core of feminism has succeeded and that the concept has passed from a movement to an establishment. Very few people are making the argument these days that it's only fitting for women to stay at home and give birth, tend to the house, and raise children. Very few people question the rights of women to do what they please with their lives, be the masters of their own bodies and property, and enjoy legal equality.
What does this mean? Well, from where I'm sitting, it means that the biggest battles of feminism are behind us and that feminists are casting about, looking for something new to do. It's an awkward state that many successful movements find themselves trapped in after their initial successes.
I'm not convinced that the label means anything anymore, given the wide variety of existing interpretations. Why not try to move on, accept that much of what needed redress has been resolved in favor of women and feminism, and deal with the remaining issues on an issue-by-issue basis? Maybe then, instead of fighting over terminology, people can say what they mean, advocate for what they believe, and possibly resolve something else?
Feminism isn't dead. It's not in need of reinvigoration. It succeeded and now we need to learn to think in terms of the present world.
