Jon Stewart sticking the knife in to JKR over "Jewish" goblins

So I've never read Harry Potter or seen more than the first movie when it came out. But Stewart seems to be describing the movie goblins rather than the book goblins. And I know from other movies based off books I've seen, that creatures in movies aren't always/usually the exact same as those described the books. So maybe these are actually identical to her descriptions but he's not saying that. He isn't saying, I read the books to my kids and her descriptions of goblins screamed 'jew' to me. He's describing the movies, and the depictions of the goblins in that wouldn't even have been her work.

Absolutely disgusting. Harry Potter is about witches, elfs, goblins, dragons for fucks sake. It's not like these are books about normal life and she just stuck Goblins in as some sort of weird dig at a particular group of people. This witch hunt is getting really disgraceful

That's disgusting and libellous.

The first Harry Potter book was published 25 years ago. Isn't it funny how people only decided the goblins were antisemitic after JKR spoke out on the trans issue?

The Potter books themselves are clearly designed to be read at least in part as attacks on Nazi ideology. And of course JKR herself has spoken out many times against antisemitism. (One of the things that made her so unpopular with the Corbynistas.)

At some point JKR will sue for slander/libel. That will need two things: to be a clear-cut no quibble case and for the defendant to be someone who can't reasonably hide behind a shielf of "the mean rich middle-aged white woman is attacking helpless little me".

Did anyone say any of this before she spoke up for women's rights? Has the LOTR franchise been criticised in similar terms?
