I was not aware people complained about goblins outside of Harry Potter, that's interesting. I think my point still stands though, also it's understandable to ask and expect people not to use goblins, it's also easy to see why J. K. Rowling got away with it: she depicted goblins the way they typically are depicted, and it's more in the realm of "unfortunate implications" than "purposefully vile worldbuilding".
