Why do we still need gender roles? 

Gender roles appeared many years ago. While men were hunting, women were looking after babies, cooking, etc. Nowadays, we can often notice that some duties of men and women have mixed. For example men stay at home and do housework but women work and provide their families. But we still need gender roles! 

We still need this separation, because for example women are't as physically strong as men are, so they can't properly do jobs such as loader, builder or fire keeper. Also gender roles genetically laid in each person and we can't destroy theese roles because they keep our habitual lifestyle. 

In conclusion i'd like to say, that we need gender roles, because this separation has always existed and we don't need to change our habbits,
