I love that aspect of fandom: brings out the failed academic in me. All of these stories, existing as part of this huge fannish history that you don't even need to be aware of to be hugely influenced by, in a completely inescapable way. It's not like any of us sat down and consciously thought 'It appears the climate is at last propitious for some classic Whovian filth: have at it, Harry!' and yet here we are. It's a brilliant and exciting thing, being part of that tide (or as you say consciously opting out of it), but it's no less brilliant and exciting to step back and squint at it.
