It is an exaggeration. I really try to steer clear of arguments made using hyperbole and I must be having an emotional response. Please accept my apologies.
This response, however, does come from a legitimate concern though. Men face a lot of stigma related to the care of children and it has had a significant effect on society. That is not an exaggeration. I feel the effect it has on fathers is pervasive. It causes men to ignore and/or dismiss their own importance in raising children. It causes women to distrust their spouses with regards to their children. It's the rationale for the discrimination men face in the family court system.
Saying "women on average may be better at taking care of young children" may seem like an innocuous generalization. How much of that is confirmation bias and how much of that is rooted in biology? Starting on this as the subject on innate gender differences is a really critical place to start. I honestly don’t know if there is a good place to start.
Maybe one day, when society has been operating with gender parity with regards to work and relationships, we can talk about innate differences in gender. For now? I’m simply not comfortable with it. Too soon.
