Whats wrong with gender roles the way they are?
The problem with gender roles is that they can be rigid and force individuals to behave in ways that may not feel natural to them. For instance, all humans experience a range of emotions. However, frequently, men are discouraged from showing certain emotions. Boys from a young age are told to not cry. It is more socially acceptable for a man to be angry, for example, than depressed or hurt. There can be unhealthy outcomes when individuals are not able to share their feelings, or even choose hobbies, professions, clothing, etc. because social norms force them to deny their human nature and personal affinities.
