So I just read your Hobbit meta and as a Jewish man I get some of what you were going through. I just want to point out that they downed the greediness and upped the heroism of the dwarves compared to the book. Also Tolkien was pretty pro-Jewish and made some apologies throughout his lifetime for the negative traits, which he claimed were unintentional. As to the scene with the dead dwarves, I saw Pompeii more, but I can see where you're coming from seeing Auschwitz. Hope that helps.
Whatever Tolkien intended, he, like many Gentiles, fell prey to some pretty basic stereotypes regarding Jews and transferred them to his Dwarves. I am not saying that Tolkien was a raging anti-Semite. That’s not my point, and nowhere have I said so. What I do want to point out, and what others involved in Tolkien scholarship have spilled extensive ink on, is that Tolkien used common tropes about Jews, including his Catholic perception of their spiritual worthiness, as fodder for creating his Dwarvish culture which, while noble, is considered in-world as lesser than that of the pure Elves who are in communion, essentially, with the Valar. I understand that he apologised, but that doesn’t make the undertones in his work invisible or something we ought to ignore, either as Jews or as Tolkien scholars (which I moonlight as in my spare academic time, having done work for Mythlore in the past).
Let me point out an article on Tolkien and anti-Semitic tropes published in a recent edition of Tolkien studies, for those curious on the state of this corner of the field, and another from Mythlore. I will be curious as to the scholarship on Jackson’s interpretation of the material.
I also do not mean to say my impression of the bodies at Erebor is absolute, but simply was my gut reaction having gone into the films with a lens of Thorin as a Jewish hero. I can see the Pompeii comparison, and that’s certainly what was intended, but the overtones to the gas chambers are too strong to ignore, given the Jewish connections implicit in the text and Tolkien’s own words.
