Celebrated novelist J. K. Rowling has won plaudits from Jewish Twitter users after her latest online battle with supporters of Jeremy Corbyn — the far-left leader of the British Labour Party hit by yet another antisemitism scandal last week after he accused “Zionists” of having no appreciation of “English irony” despite “having lived in this country all their lives.”

The British author — who created the Harry Potter series and also writes crime fiction under the pseudonym “Robert Galbraith” — has long been a critic of Corbyn, whose three years at the helm of the Labour Party have mired the party in an unprecedented crisis with the Jewish community in the UK.

In a Twitter exchange with a supporter of Corbyn on Sunday, Rowling quoted extensively from the classic 1946 essay by the French leftist philosopher, Jean-Paul Sartre, titled, “Antisemite and Jew.”

“They (antisemites) delight in acting in bad faith, since they seek not to persuade by sound argument but to intimidate and disconcert,” read one quote from Sartre selected by Rowling.

The argument started after a pro-Corbyn Twitter user, Simon Maginn, aggressively challenged a post about Corbyn from a Jewish user. “Explain your patently synthetic outrage,” Maginn demanded.

Apparently reading the exchange, Rowling leapt in, telling Maginn, “How dare you tell a Jew that their outrage is ‘patently synthetic’? How dare you demand that they lay bare their pain and fear on demand, for your personal evaluation?”

Rowling continued: “What other minority would you speak to this way?”

The weekend’s exchange followed an even blunter tweet from Rowling earlier this month attacking the rising antisemitism in the Labour Party.
