I agree. Gender differences seem to be exaggerated, while in upper classes women and men converge to androgyny. One contributing factor is that surviving on low incomes requires more differentiated roles (care taker vs manual laborer).
As a man who has been the primary parent for most of my children's lives (my ex is not very good with older children) I find the assumptions people make annoying. People are surprised my younger daughter lives with me rather than her mother. They struggle to find words to describe a man as primary carer.
I think this is damaging to men - bringing up children is incredibly rewarding and men are given a smaller role in it. Its damaging to women too.
Women do want careers as good as those of men. There are huge efforts made to equalise numbers of women in various careers (especially high paying ones and in senior positions).
I do not see how this can work without men taking on more traditionally female roles.
IMO we should make it more acceptable for men to be stay at home dads, just as we have made it acceptable (and entirely normal) for women to do a lot of traditionally male jobs.
Why would anyone choose the role of a provider if they aren't under a huge biological pressure to be one? All it does is offer an alternative way to slightly increase dating prospects.
But some of those that still do are and always have been dominated by women: nursing for instance.
I would say that nursing is a good example of a female dominated job that ought to have more men in it, as greater strength is a huge advantage when, for example, moving/positioning someone.
