I don't think women should tolerate even a day of a sexist man at home<
I think you also note somewhere that women should marry a non-sexist man. Who are these sexist/non-sexist men who are someone else at home than they are in the workplace? The same men that are sexist in the workplace are sexist at home.
Secondly, in my opinion, I actually think non-sexist men are few and far between - they may not be intentionally sexist, or they may think they are not sexist or they may just be plain selfish; but societal expectations of men and women's roles are so socially ingrained that it sneaks in even where there is supposed equality. Plus, problem is these sexist men don't come stamped with a big sign on them - some of them even talk the right talk, they are respectful and treat you like an equal until children come along. Then somehow, it is like feminism never happened. Even if you both work full-time and are paid the same. Been there, done that. So, what happens if you don't tolerate it and end your marriage (been there and done that too) - they don't suddenly turn into your 50/50 shared care father, nope, you have answered all their prayers because you legalise a situation where you ARE the main carer. Super, they are off the hook, but get to be great dad EOW and single man the rest of the time. No sexism there, YOU initiated the separation, suck it up.
Or my experience from my first marriage - didn't tolerate lack of support - very quickly found I was dispensible for a younger version of me who would take on the housewife role.
I do not for one moment regret standing by my principles and ending the marriage (or in the case of my second marriage, not being able to carry the relationship and H's needs as well as everything else, so there was no choice really, I would not have survived otherwise, and I don't mean that lightly), but it is a lonely path to follow. Let's not pretend otherwise. It was the action of last resort.
For what it is worth, I'm trying out an experiment whether the not tolerating sexism and separating has worked over the long term and whether a more equal balance can be negotiated three years later. The jury is still out.
That is my first point.
Second point: "Every woman who goes part time damages other women".
I will add to AskBasil's response, which I agree with, that this statement not only ignores structural inequalities, but the fact that equality is not about working all the available hours for more and more money. It is recognising that people are different and have different needs. My needs changed professionally when I had DS who has special needs and did not adapt to childcare. I had to change path quite substantially within the same field. That does not make my contribution to professional life any less, in fact it makes it more - because it is possible to say, there is another way of viewing/of doing things. It is not one model fits all.
Yes, we all need money to live, but actually, I also need time to breathe, to be, to notice the colours of the leaves, to take my children to the park, to know what they are doing at school - and let those experiences shape the person I am at work. I don't care if my DD outearns the men, I care that she is independently financially secure, yes, but that also she has a fully-balanced and rounded life which allows her to develop as a person, however that person is and to be comfortable with that person and to stand by the integrity of that person. The same I wish for DS.
I know I have not contributed to much of this thread, and I am jumping in with an essay. But please, please don't negate the experiences and choices of other women (and men) by myopic vision. One of the most successful women I know worked three days a week until her children left school; and explicitly said, I need to be there for my children as well. Does she earn the same as her male peers? No idea. Does she have a more balanced life than many of them? I think so.
(By the way, I still work FT as a single parent of two with little outside support; if I could afford it, I would work 0.75 in a flash! I am exhausted).
