Harry Potter author J.K. Rowling fired a shot at a British politician Wednesday who expressed dismay over the stabbing attack in Golders Green, London, that injured two Jews.

“The stabbing of two Jewish men in Golders Green today is deeply shocking and a stark reminder of the very real danger antisemitism poses on our streets,” Zarah Sultana, a British MP, posted on X. “My thoughts are with the victims, their loved ones, and the wider Jewish community.”

“No one should be targeted because of their faith,” she declared.

Rowling blasted back hours later.

“@zarahsultana I assume this is a different Zarah Sultana MP to the one who was recently filmed clapping along to loudspeaker chants for intifada, on a street in Surrey,” she posted on X, linking to a Telegraph article describing the incident, in which Sultana was filmed chanting along to a slogan about an intifada just hours after the Metropolitan Police and the Greater Manchester Police issued a joint statement saying such slogans should be banned.

Sultana didn’t hold back.

“I actually care about all human lives Joanne, but I’m wondering if you actually do?” she snarked on X. “Have you mentioned the genocide of Palestinians even once or do their lives not matter to you?”

“Using today’s events to score political points is disgusting. Shame on you,” she said, while scoring political points herself against Rowling.

Sultana’s sympathy for Jewish lives only goes so far, however. A few hours after posting her “thoughts for the victims” of the stabbing attack, she slammed the Coventry City Council for investing in Palantir Technologies, a company she accused of conspiring with Israel to kill people.

“Labour-run Coventry City Council has just handed £750,000 to Palantir — a company that profits from hunting immigrants for ICE and produces ‘kill lists’ for the Israeli military,” she wrote. “A company lobbied for by Peter Mandelson himself. Shame on them.”

For many British Jews, however, it’s the creator of the beloved children’s series who stands on the right side of the debate.
