An Alternative to Feminism

With every woman seemingly announcing that she's a feminist nowadays, I feel like there must be some alternative idea that you can support. Why else would women feel the need to announce that they believe in the equality of the sexes.
Are there really women out there who don't believe in that philosophy? I can (almost) understand a man not being a feminist. With his penis and his big, fancy job and his killing of small bugs, he might believe that men do deserve more than women. But a woman who feels the same way?
Is there a woman out there who walks around thinking, "I don't have a penis or kill bugs or forget anniversaries or shave my face or wear baseball caps, like, every day, so I'll go ahead and work the same job as a man for less money. That's totally fair."
Therefore, if women nowadays are "coming out of the closet" so to speak, what did they believe before? What's the alternative to feminism?
1. Maybe these women didn't believe in the equality of the sexes because they felt women should be pad more than men. They thought, "We have vaginas, lactating nipples, smooth legs; we carry humans around inside of us for nine months; we cook, clean, tend to the children, pay the bills, in some cases bring home the bacon, and still find time to look presentable for that one night when the man actually takes us out." (Hmm, they might be right on this one. Perhaps we should pay women more.)
2, Maybe these women don't want to be defined as women and, therefore, only see one sex. If there were only one sex, then equality wouldn't be needed. Like, how the shortest distance between two points will always be a straight line so you don't even need to discuss it. If only one sex existed, being a feminist wouldn't even be a thing (kinda like the word zizaroni in that AT&T commercial).
3. Maybe the alternative to feminism is feminism. Perhaps they've always been feminists, but a. didn't know it or b. were too scared to admit it. Like homosexuals in high school in the 90s, they hid in the closet, hoping no one would find out their dirty secret. But now that the tide has turned, now that being a feminist is cool, they want to shout it from the rooftop.
However, maybe there's no alternative to feminism. Maybe these women thought feminism was a dirty word. Before 2014, a.k.a. the Year of the Feminist, those women were thought of as bra burners with hairy armpits who hate men. Now we know differently. Feminists don't hate men; they just want what we already have (minus the penis).
Hopefully, someday in the future women and men will play on the same team. Today, at least we're all playing on the same field, and that's a good start.
