As I said, those aren't the only characters I'm talking about. And whatever the justification for their behavior, it has led to a stereotype throughout literature and media that "insane/mentally ill girl" is "wide-eyed poetic babbler." Moreover, there were minimal to no significant other indications of mental illness for those characters *beyond* their Naive Psychic Babydoll behavior.

And it's frustrating, and sexist, and a bad stereotype.
