Why we still need gender roles?

    Nowadays, in our society we have many prejudices and stereotypes about gender roles. Such as "gender roles are definitely important for the society" or "gender roles establish our identity". I would like to discuss the pros and cons of gender roles being important. 

    Firstly, i'd like to talk about pros. Many people think that 'it's in our nature'; that on the one hand the major part of women were born with the nature of being caring, domestic etc, and on the other hand the majority of men are more used to protecting, providing.  Also there's an opinion that gender roles are very important for the society. Without them there'll be chaos. 

   Secondly, i'd like to say about cons. Gender roles are outdated.  They aren't important for the society (68% of todays families aren't traditional). Every one is a very complex and contradictory, we don't even understand how does our body(especially brain) works, so how could we state how each person should be. 

    To conclusion, i'd like to add that in my opinion gender roles are absolutely unimportant nor to the society neither to humans nature at all.
