It is stupid to give children gender-neutral toys to play

Because proper gender development is important for survival and developmental/cognitive skills.

Because humans are born undeveloped, parents and others provide extensive socialization, generally intended to promote personality traits and skills they think will help offspring in their future adult roles. To the extent that women and men have different adult lives, caregivers tend to promote sex-typical activities and interests in children – dolls for girls, toy trucks for boys. Conventional socialization can set children on the route to conventional career choices.
