Biological women are pre-wired to generally be more caring towards others since their job was to carry the baby and then in most societies they would be the most active caregiver towards the baby. Men on the other hand generally went out to hunt, and were far more exposed to competition with other men. They were also the protectors of their family or community.

I do think this is stupid, but there is something to women being more left-wing/liberal and less right-wing/conservative than men in voting patterns across the developed democratic world, from Sweden to Taiwan.
