RE: Do Parents Stereotype Their Children's Gender?
Gender stereotypes are adaptive mechanism. By acknowledging the inherent physical superiority of the male children, the females focus their efforts in counterbalancing their physical disadvantage via development of other means of interaction. Adult men tend to communicate differently from women, with men experiencing difficulty verbalizing emotions. Could it be that women learn and develope emotive language as a counter-force against male physical dominance? What would the modern West produce, as they forcibly reject the very fact of biological differences between the sexes? Is the rampant youth violence and "epidemic" of ADHD observed in our modern era a consequence of penalizing "boyish" activities of physical nature by predominantly women educators?
Some of the research agrees with you. Here's a rather lengthy quote:
