I read an article on this and I could find nothing that she said there was antisemitic. There was a bit about coming to the surface the concept that Ben Shapiro is a Jew and she is a christian. The two religions do have different beliefs when it comes to christ. But saying Christ is King is not antisemitic.
There’s a meme going around that I can’t find on short notice, which goes something like:
Anti-semitism used to be where someone disliked Jews. Now, it’s someone who Jews dislike.
Christus regnat!
“But saying Christ is King is not antisemitic.”
Absolutely correct.
This was the straw that broke the camels back:
But Owens’ rhetoric about Jewish people appeared to reach a new low this week when she liked a social-media post asking conservative rabbi Shmuley Boteach whether he is “drunk on Christian blood again”—an overt reference to the antisemitic “blood libel” canard that has regained popularity on the far-right via QAnon. (Days earlier, Owens dabbled in other antisemitic tropes by suggesting there’s a Jewish “gang” in Hollywood.)

In her way out she referred to Jews drinking the blood of Christians.
