The toy you are going to buy is a sexist toy, a toy that perpetuates stereotypical gender roles and discrimination they entail. The toy industry creates different products for girls (those related to the world of home care and fashion) and boys (those that refer to public space: sport, construction, war, etc.), showing it as a natural thing, being a cultural construction: the separation of male and female world. Moreover, this is nothing more than a marketing strategy of large companies to secure their benefits.
Toys convey a conservative, an obsolete ideology. It is not "natural" that girls play with dolls in order to prepare to be loving or attractive women mothers. Nor is natural in boys compete with others, struggling to impose their rules or playing to conquer lands and kill its habitants. The sexist imagery that promote most toys is consolidated through a variety of materials; colors, shapes and sizes, and symbolic, for example the language used to advertise feminine toys is sweet and tend to be loving and use diminutives expressions. Even those toys that seem to be not directed to a specific genre, such as puzzles, often have their female version. Besides the division of roles, children learn the different assessment that society makes them: everything related to "feminine", in this case toys for girls, is devalued and relegated to a second level, behind of the "masculine".
How can we create an egalitarian society by educating new generations discriminatorily and by buying sexist toys? How do we pretend of avoid eating disorders in adolescents if a few years ago were playing with barbies skeletal and unreal? How to complain about youth violence if parents give children toy guns? The worst barrier that children face is marked bounded by the cultural stereotypes of their parents. Today's games are the behaviours of tomorrow.
