The Holocaust was the killing, on an industrial scale, of the Jews of Europe.
Yes, there were many other victims of the Nazis but the primary reason for structures and processes of the Holocaust, one might say the only reason, was to rid Europe of Jews.
I do think that narratives that want to centre other groups are a really vile piece of anti-Semitism beside which writing about some goblins (because our cultural folk tradition has these goblin thingies in it) doesn't even register.
Talk about fucking irony.
