Mayor Bill de Blasio said Tuesday that anti-Semitism is a “right-wing movement” — while rejecting a claim that the left plays any role in discriminating against Jews.

“I think the ideological movement that is anti-Semitic is the right-wing movement,” de Blasio said at a Brooklyn press conference Tuesday about the increase of hate crimes in New York City. Hate crimes against all minority groups are up 64% compared to this time last year. Anti-Semitic incidents have spiked by 90%.

De Blasio said he did not agree with a claim by a reporter that there is also rising anti-Semitism “on the left in the BDS movement and around the world.” The Boycott, Divestment and Sanctions movement is a largely left-wing campaign to ban Israeli products.

“I want to be very, very clear, the violent threat, the threat that is ideological is very much from the right,” de Blasio said, adding that the perpetrators trace their history back to Nazism and fascism.

He was speaking specifically about national and international incidents.

The remarks drew immediate blowback from City Council members on both sides of the political aisle.

“I don’t agree with the mayor,” said Chaim Deutsch, a Brooklyn Democrat.

“I have not seen any white supremacists coming in here committing these hate crimes,” he said.

Indeed, NYPD Chief Dermot Shea said at the same press conference that perpetrators of hate crimes “run the gamut” from teens, to people with mental illness, to first- time offenders, and career criminals.

For example, a 16-year-old recently turned himself in for punching an Orthodox Jewish man in the head in Williamsburg.

Staten Island Republican Borelli called the mayor’s position laughable.

“A simple look at where anti-Semitic hate crimes have occurred just disproves this– unless you count central Brooklyn as the home of a vast right-wing conspiracy,” Borelli said.

“Bill de Blasio regularly says stupid things, but this is literally the stupidest effing thing he’s ever said,” Borelli commented.
