The qualities associated with girls' toys, such as nurturing, are generally seen as inferior to the assertiveness of action figures for boys. Cordoning off particular activities, behaviours and ideas to one gender ignores that there is no justification for doing so and limits the potential of both boys and girls to develop their skills and imagination freely.
In the 1970s, women entered the work force en masse and the women's liberation movement overthrew the ideal of the pretty, dutiful housewife who encapsulated women's contribution to society
During that time, the ideal of being a housewife was considered being a lessor approach or ideal for life.
It would seem, the very people who started this was somewhat sexist as well, and hadnt fully grown out of their perceived ideals as well.
When youre scoffed at for being a mother, staying at home and taking care of a household and the children as the primary caregiver, it led many women away from such ideas, even those that prefer it.
PS this game wouldnt still be being made if girls didnt want to be girls and boys, boys
