Demanding Jim Crow casting requirements for a show on which the concept of race applies to elves and hobbits indicates a rather profound “obsession with identity issues that only go skin deep.” The primary tensions in Middle Earth are among races
even more fictional than the ones that divide contemporary society. The fact that its cultures are inspired by real-world history does not rationalize imposing patterns of migration, conquest, and exploitation onto a fictional universe in which they did not take place. J. R. R. Tolkien’s tendency to essentialize his fictional races, giving them intrinsic moral qualities, is the subject of a great
deal of research and commentary, but that’s not really the issue here. There are stories set in universes where race works similarly to how it does in contemporary society and where it should influence casting choices, but this isn’t one of them.
