so I don't know exactly how you want to start it or what exactly is is about, but I will give is a try.
Girls like pink and boys like Blue, Girls play with dolls and boys with cars. This is how society has always portrayed these two genders, creating a gender stereotype.
you can add a 3rd sentence and say
But can we break it? and then start your paper
again I don't know if this is good enough but I hope it helps.
