Perhaps simply due to me being Asian, I don't get the value of discussing sexism at all.
Sex being misrepresented is itself an individual issue that stems from underrepresentation of historical aspects. Its nature is no different to underrepresenting slaves, cultural aversions or religions.
I'm all for the game representing more historical aspects including that of different sexes. But calling something sexism is counterproductive due to how accusative this word "sexism" is. It's a word without substances other than only being used for pointing at someone and accusing him that he's wrong to mistreat women.
In the Antiquity, women had very specific roles in the society. For example, Greek women would be the backbone of economy and we have this word "economy" thanks to this specific role ("Oikos" means home, as mentioned previously). There were also the Heraean Games for women since the Olympics were reserved for men. There are also records of women participating in wars but not common. Athena Promachos, the patron goddess of Athens, was herself a female warrior. And of course we had the Amazons. And we also had Gladiatrices in Rome.
But then also Roman women did not have names. They were only referred to by their father's name and a number. Julia Prima, Secunda and Tertia respectively mean the first, second and third daughters of Julius.
Greek women had their own names but were mostly referred to by their husband's, brother's or father's name.
Women in antiquity is such an abyss you can invest so much time and efforts in and never get any meaningful game mechanic. It's much simpler to consider a whole family with men and women as an atomic unit.
