I don't think housewives getting hate is a recent thing at all. It's been going on for decades, since at least the start of second-wave feminism, and in more limited contexts much earlier than that. Perhaps hatred for housewives is becoming more visible, since Millennials are now the norm in society, and Millennials grew up in a cultural environment that almost universally vilified housewives. But it's definitely an old narrative; older than any of us Farmers have been alive.
What I don't get about housewife hate is why contemporary feminists value working outside of the house over staying at home with the family. On a philosophical level, it doesn't make sense; the principle reason why "traditional men" left the house to mine coal, freeze their asses off on fishing boats, and get mauled to death by bears, was in order to provide the necessary resources for their families. No family? No need to work. Work is subordinate to family. Family is not subordinate to work.
The whole "men's work is a privilege, women's work is slavery" narrative is completely inverse of historical reality; in actual fact, it was female privilege to lead a life of leisure and familial fulfillment, while men slaved away in the fields and forests, oppressed by duty and necessity. And while I would certainly agree with the liberal feminist argument that women should be permitted to work if they want to, just as men should be allowed to mooch off women if they can find a woman who'd put with it, it's insane that people would go any further than that - asserting that families are slavery, but work sets you free.
That's on a philosophical level. On a practical level, this madness makes total sense, especially if you go back and dig into the writings of 19th and early 20th century Modernists and Progressives. I'm convinced that the anti-familial rhetoric of Current Year started as the result of a deliberate effort, by wealthy and well-educated collectivists, to both encourage the growth of an industrial taxbase, and to discourage the social independence of family units - conditions which the welfare-warfare state could then exploit, for the good of furthering the Progressive cause. Over the decades, these Trojan Horse memes trickled down into the minds of the less intelligent, less well-educated Activist Class, hence why we now have so many middling academics who take it as an absolute article of faith that being shipped off by oligarchs to get shot at in Afghanistan is "a privilege", while getting to stay home and cook a nice meal for the people you love is sexist, toxic, problematic slavery. Does it make sense philosophically or intellectually? No. But the reason why these people have been trained to think that way is perfectly apparent.
It's no longer a case of a couple posh Oxford dons sitting around the fireplace, sipping brandy, saying "yes, well, the family unit is wonderful and all, but wouldn't it be ever so nice if the proletariat were a little more dependent on us Eton boys? Who could then utilize the principles of Scientific Management, in order to improve their lives?"
Now it's a bunch of field niggers, who want to be house niggers, lecturing their fellow field niggers about how we all gotta stop crying about being separated from our spouses and kids, cUz faMiLieS aRe stRucTuraLlY sExiSt.
