I think most of us can agree that the only thing wrong with sex roles is when they are expected and enforced. If a couple decides that they want one of them to be a stay-at-home parent and that—for whatever reasons that make sense to them—they decide that the husband should be the one to go to work daily and the woman should be the primary childcare person, that's their right and it's really nobody's business but theirs.
One can argue that the woman is giving up career-building years of her life, but couldn't we say the same about the man if he is the one staying home?
Now, let me bring up something obvious which, nevertheless, tends to be controversial in some circles, which is that men and women, as the product of millions of years of evolution and as such tend to have some ingrained, inherited, hard-wired tendencies and talents which result in common sex roles.
When I say these sex roles are common, I don't mean to say that biology is destiny, for we can, where we wish, defy these roles. However, it's no one's duty to defy them.
One of the unfortunate effects of the rise of feminism in the 1960's and 1970's was that women seemed to feel an obligation to pursue a career outside the home whether they wanted one or not, and to measure their success in terms of their pursuits outside the home.
My ex went though that period. She is very smart and got an MS in computer science, and became a well-paid engineer with a talent for reading machine code (1's and 0's). She pursued this career while our daughter grew up.
About that time, she quit that job and married a friend (we had been divorced for a while by the time that happened). Now, she hardly spends any time online and certainly does no software engineering.
I kind of wonder if she now feels her career years would have been better spent being at home to be closer to our daughter.
I don't know if it's still the case, but when I was growing up in the Cleveland, Ohio, area, there was junior and senior high school, no middle school, at least in the public school system.
You're an example of how females are wired a little different from males.
Someone said (and of course this is one of those gross generalizations with a shade of truth in it) that, "A woman will make a hut for her family and move into it and turn it into a home. A man will make a hut for his family, help them move in, and then go and build another hut."
Perhaps you could look at a different, unrelated culture in which women are also oppressed and compare. It's a difficult and complex task to sufficiently well control for enough factors that you can isolate real causes from coincidences.
