Using the defense of "a children's story" stopped working after the third book. The material in the others is most certainly not for children, it's for the children that started with the book, then were 12, 16, 18, 20, whatever.

She has very detailed notes on all her characters, even the low radar ones that may or may not be mentioned, which isn't abnormal considering the scope and size of all her books. Being very detail oriented I can see how Dumbledores sexual orientation might have been brought up in a few personal notes when working out his relationship with Grendelwald or just in general. I often wondered why he didn't have any children, or some sort of romantic backstory wasn't brought up to explain the fact that there was never a Mrs. Dumbledore.. or that he didn't throw it to McGonagal.... errr... It could have just as easily worked out other ways, but she wrote it so it's her call.

Makes me wonder about Professor McGonagal now!

I always thought of Lee as Token. He's the man. I don't think his color is actually said in the books, only that he has dreadlocks. He is portrayed in the movies as being black though.
