'Brave' sexism post

what i learned:

• that they call her a princess
• that she hates the dress in the movie
• that they even made a doll of the character (i.e. im a guy don't care about dolls)

opinions:

• i dont like that Disney isn't using the original idea for the character as a strong willed woman
• i do like that people are fighting for the original concept of the character to be used in the doll

question: why did Disney make it so girly in the first place?
