The liberation bit seems incredibly utopian to me though.
It doesn't mean that we can't work for equality, too.
Think of it as a compass needle. If you want to get to the North Pole, you walk north. You may not ever get there in your lifetime, but it will become noticeably cooler while you walk north, and you will have walked part of the way, so your children don't have to walk all of it.
If you walk without a compass, you might end up walking to a place that is cooler now, because there's wind or shadow, but lies farther south and will get uncomfortably hot, soon.
I hope that metaphor works.
I am realistic about the likelihood of women's liberation during my lifetime, but I consider it important that we make progress, or at least don't move backwards.
