As a disclaimer, I am not asking whether or not Rowling is an antisemite. She has commented on antisemitism before, and the answer to the question of her deeply held personal views would almost certainly be opinion-based. I am wondering only whether or not she addressed the specific question about the Goblins of the Harry Potter universe.
Basically, it's this: Rowling's Goblins raise a very understandable red flag for quite a few Jews. Their faces are essentially dead ringers for the common offensive caricature of a stereotypical "Jew," complete with the long nose, wrinkles, the evil smile, and the long grabbing clawed fingers. They love money / coins, and hoard gold. And, rather than just burying or hiding it, they work within the established financial system as bankers, and they wear suits. In the 21st century it's difficult for this to simply be waved away via visual fairy tale elements, so I am wondering whether or not Rowling has commented on this specific part of the Harry Potter franchise.
