Kinda a characteristic of how elves are supposed to be. They were originally written to be this inherently 'better' race because they are older. Any look at that that isn't from the view of essentialism or blind nostalgia would see that as the making of very arrogant and self-righteous people. It's one thing if you are dealing with the characters as individuals but if you're looking at a setup for their culture and you look at the original setting while having a sense of self-respect, you would probably feel like they were assholes.
