@Matthew Yup: Thesis · Antithesis · Synthesis. Funnily, many leftists claim their idea of "socialism" is already a synthesis, and I struggle to explain them it isn't. Some kind of multi-faceted society where we'd form voluntary collectives maybe is, but I'm not sure if and how this would work out in the long-term.

@muyuu So you're essentially saying that because women have to negotiate more "off-time" than men, they'd either be incentivized to not  have any children at all, which would result in the human species to become extinct, or they are disadvantaged, as I said in my OP. "And it has been so for centuries", this is the patriarchy that many "progressives" want to get away from.
