Imo, analysing literature is mostly a subjective exercise, and your analysis exposes you and the author, your relationship with their words. I often wondered what the writers would make of our analyses when we studied texts for o-level.
Language was created for communication but can be given contextual interpretation, (and the corresponding exhorbitant legal fee).
Gwenog's outstanding analysis rings as true as Yanksplaining's.
Creators put a part of themselves into their creations. This of course means that all jkr's works are her horcruxes, little pieces of immortality, and she only needed to kill off fictional characters in the making of them. That's an awful lot of book burning before you can kill off the big bad witch!
I remember reading the threads here speculating how the story would unfold with each book as they were being published, and wondering if jkr was reading or even contributing to mumsnet. I'm sure at least one person raised the idea of Harry the horcrux before the plot was fully formed in the books.
We all watched the child actors growing up in the spotlight and tbf that's not an easy thing and there have been demons for them.
I'm in awe of the complexity of jkr's brain, her work ethic and her wordsmithing.
