I remember sitting on a panel at a Doctor Who convention in 2013 when the question was asked: “How would you feel about the 13th Doctor being a woman?” At the time, I hadn’t given it much thought. I answered something to the effect of, “I’d prefer the Doctor to be a man. But, I would be fine with it if it happened.”
“What age should my son be before I show him to Doctor Who?” “My daughter is 6, she’s ready for Harry Potter, right?”
I’ve attended and participated in numerous “Introducing Kids to Fandom” & “Parenting Geeks” panels at conventions that have featured child psychologists, educators, religious figures, writers, and other stay-at-home parents. The one definitive thing I’ve learned is that everyone has an equally strong, but wildly varying opinion on these types of questions.
