I think this comment betrays a lack of awareness of the history of feminism and the ways in which it has developed, though.
I am not sure when you are finding a definition of feminism which meant women’s struggle to be fully emancipated into society alongside men. And even if you are finding this, what do you think have historically been and still are the barriers to this full emancipation?
Even if you go back to the late nineteenth and early twentieth century when women were campaigning for the vote and seeking access to the professions alongside men, this was with arguments about women’s role as mothers and what they brought to the public sphere. In the early twentieth century, women were also concerned about and campaigning for better pregnancy and maternity care because of the high numbers of pregnancy losses, particularly among women in poorer socio-economic circumstances. Once you get to the 1930s, birth control and abortion were fully on the agenda. This was because, as I said upthread, one in five maternal deaths were from illegal abortion.
That’s before you get to second wave feminism where abortion rights were a torch paper, if that is the right expression. Although in fact, the current abortion rights we have were pretty much in place due to campaigning and work since the 1930s and the role of key doctors. Second wave feminists also campaigned for childcare and organised play groups for their DC as there was no provision, so it was not just about limiting pregnancy and birth.
My point is that there has never been a time when women’s position as the sex which bear and mostly rear children has not been central to feminist thought. This is because it is this point - that women are the sex which bear and mostly rear children - which historically prevented and still prevents their being fully emancipated into society.
That is my first point. The second is about the various strands of feminism - liberal feminism, socialist feminism, radical feminism, I am sure there are more but these are the ones I can think of of the top of my head. Feminism has always been a much broader church than you describe, and it is okay to disagree with other feminists. The history of feminism is full of disagreement about how best to achieve equality.
