"Women never went to war to earn the right to vote!"
"Isn't that because men banned them?"
"NO NO NO! Squad coherency...uhh, gender roles!"
Please cite your sources that women are forced to work after childbirth, and are unanimously saddened by it.
Please cite your sources that prove being a parent to your children is a job solely for mothers. The link provided doesn't state that fathers are unnecessary, but that single-mothers vs married couples involves a lot more extraneous variables than the simple absence of a father figure, (omission of father's income, omission of father's family support, the additional time of having a second partner, as it notes gay and lesbian couples fill both roles well in a typical relationship.) This is debatable and relies on the ever-ineffable concept of what "good parenting" means.
Please note the historical document men and women made this "deal" on to keep the species going. Your cited issue of elderly populations is not an issue of Feminism, it's an issue caused by longer lifespans. We are no longer in an era of high mortality, we are suffering the opposite, and stabilising population levels across the globe will help us in the future immensely.
You say "something men did to women, something something misogyny," but don't cite what you're talking about that is misogynistic. Empirical facts are: men own the majority of positions of power in the world, men dominate the land ownership, and in the lists of the rich. That's misogynistic.
