Wow, that is just amazing.
Doing a literary critique of a character in a book does not mean that you believe in the literal existence of this character, and believing parts of a book in no way means that ALL of the book is true.
Gone With the Wind made some factual statements concerning the Civil War, this doesn't mean that everything written in the book is factual. Discussing this book and Scarlett's motivation for some of her actions doesn't mean that I believe that Scarlett is or was a real person.
