The problem is the lack of nuance in this debate. It's either "natural differences" or as you said > another possibility is sexism in the way we raise boys and girls differently. Making this a binary choice is unnecessary, dangerous and in no way better than the "conservative" notion that women belong to the kitchen. Let's assume everything is solely based on social factors, adult women in this generation still won't have control over the way they were raised. It's unlikely that they will suddenly drop the behaviour they accquired over decades. And even if they could, why should they? If they're happy with their choices let them be. Instead we should work to value caregivers more, regardless of gender.
