can a girl be a superhero?

Growing up in a very sexist society can be extremely rough as a young girl or boy. Girls are princesses and boys are superheros....you don't really see them switching them up!  Why cant a girl be a superhero? Its hard to think that such a small part of our lives can impact on what a man and women choose to become when they are adults.  Women should stay at home is the thought that some people were raised to know.  Now with the freedoms of women a man can be a stay at home parent while the mother is the bread winner.  I thought this picture was a perfect way to a show that a girl can be masculine and feminine at the same time!!!
