Anti-Princess Movement

Have you heard about the Anti-Princess Movement? You can do a quick Google search on the topic and come up with a host of opinions. But the essence of 'the movement' is this; Disney princesses teach little girls to be weak, fragile creatures who think physical beauty and finding a prince are the only sources of happiness for a girl. Disney princesses in particular are getting the brunt of criticism. I, however, would like to offer an opposite opinion; why Disney princesses can be a model for little girls, or at the least a teaching tool.
