I'm assuming that's sarcasm, but just in case.

It's the allegations that the series is referencing Jewish people are goblins, not that the goblins are Jewish. It's making the insult about noses and that they are greedy. Going back to old caricatures that Jewish people are goblins and bad.

I don't think that was the original intent and goblins were picked because it's a fantasy world, but I could be wrong. If that was the intent, it's fucked up, but don't think that's the case.
