Heck, the reason she's known as J.K. Rowling here is because Scholastic was afraid boys wouldn't buy a book by a woman. And I don't know that she's even fundamentally free of those attitudes herself, though one of the things I love about the books is how the characters are so real to us and to her, and how even if she doesn't know how to describe them, 90% of the time she knows and is respectful of who they are.
