Imagine a society where choosing to be a stay at home dad would be totally fair and OK

That's difficult to imagine though, seeing as our government sees anybody who stays at home as bad, because they are not taxed for all that work they do. If parents do not have one that stays at home, then more taxes are accrued, not just from both parents, but also from the childcare provider the parents now pay to do the essential task of parenting.

yes, essential! As if childcare is easy! As if it isn't one of the most obviously important influencers on the future of our species... "Give me a child for the first 7 years, and I'll show you the man."

Even if MRA somehow had it's heyday and everyone got redpilled, it would still involve a serious, slow, sometimes bitter change in our collective consciousness about what it means to have the privilege to be a stay at home parent
