These aren't outdated gender roles. Girls still love the Princesses, they're just giving them a place to meet them. If I remember correctly, The did teach the boys how to present themselves as gentleman as well, when the Faire was in the theatre. Also they sold shields and swords. I'm sorry, but at the end of the day, most boys aren't gonna go for the Princess stuff. It's just a fact. It's not reinforcement, it's recognition.
