Having and expressing negative thoughts and opinions toward J.K. Rowling and stories that exist in the wizarding world in general does not cancel out your identity as a fan.
Since the beginning of time (and by time, I mean “Harry Potter and the Sorcerer’s Stone”), I’ve always thought of Dumbledore as not only wise beyond his many, many… many… years, but as someone who was in a sense “ethically and morally superior”. He was the Wizard who could do no wrong; he was a role model, in particular to Harry, and as Headmaster of Hogwarts I had assumed a certain level of credibility attached to his name, at least to some degree. But as we continued to read on through the books and as the final pieces of the story fell into their rightful place, I found myself feeling a bit unsure of exactly where Dumbledore stood in my lineup of favorites. I mean, who was Dumbledore, really?
