And the great failure of feminism (all waves, all subtypes) so far is not really having any answers for the motherhood issue, except not having any children, or trying to juggle motherhood and career (and often doing less well at one or both, while paying lower waged women to pick up some of our household/childcare slack (something I, the daughter of a cleaning lady, am deeply uncomfortable with).
Mary Harrington is good on this.
But I find the criticism of women who "pay lower waged women to pick up some of our household/childcare slack" is always unfair. We don't castigate men that way; we rarely rub their faces in the ways that they have a career by exploiting the women around them, in such a public self-critical way.
I think the difficulties 2nd wave feminism had with motherhood are quite understandable. I was a teen in the 1970s, and started university in the late 70s (I'm at the VERY tail end of the Baby Boomer generation). I can still remember the introduction of equal pay, maternity leave, equal pensions, the removal of the requirement that women resign permanent positions on marriage etc etc - all the "equality feminism" moves to remove overt discrimination against women.
This was the necessary push to make women "equal to" men (although I do remember wearing a radfem badge which said "Women who aspire to be equal to men lack ambition"). Although there was plenty of debate about it at the time, believe me!
And to make women equal to men, reformers & activists had to show that women were just the same as men - that our role in reproduction did not make us so very different from men in public life, in the workplace, in education.
This was because sexual difference had always been used against women to "prove" we were not fit to do all the things men did.
So we squeezed women into a public, working world which has been organised around the male body, the male role in production & reproduction, and a "heteronormative" male life pattern. Women couldn't mention sexual difference, because that would just be used as a stick to beat us with "Aha!" the union bosses would say (and this is why Labour is so crap about women now, I think) "you can't do the same job as men."
The next stage in the revolution (and women's liberation is THE revolution of the modern world) is to reshape public life around women's bodies, women's life patterns, and women's role in production & reproduction.
Which is why the current vicious assault on the very fundamental definition of what it is to be a woman or a girl is so appalling.
