JK Rowling has revealed that she always thought of Dumbledore as gay. I like the words she used. She didn’t, as has been reported, say that he is gay. She said she thought of him as gay. There’s a distinction there. After The Deathly Hallows came out she gave out a few ideas of what “happened” to the characters after the story ended. The thing is, she didn’t write them into the story, just like Dumbledore’s sexuality. Whatever happens between and after the pages is still open for you to read and imagine whatever you want. An aspect of postmodernism states that literary analysis goes beyond even the intentions of the author himself. Such-and-such is what she thinks happened to the characters, but by not writing it into canon she’s saying that your imagination is just as good as hers.
