Boys playing with "action figures" and girls playing with dolls (baby or Barbie) are TOTALLY different.

Read Christina Hoff Summers' book "Who Stole Feminism?" In it, she tells the results of a study by a toy company to see if there really was a gender difference in young children, and gave them equal toys.

As a little girl, I played with G.I. Joes.
Well, I borrowed my neighbor's so I could use him to marry my Barbie.
