Exclusive | Unhinged man dubbed ‘MackNazi’ terrorizing NYC, ripping down Israeli hostage posters

An unhinged, Israel-hating dog walker who lives with his TV-actress sister on the Upper West Side is terrorizing the neighborhood, repeatedly ripping down Israeli hostage posters and allegedly assaulting anyone who dares get in his way, The Post has learned.

Since Hamas’ Oct. 7, 2023 terror attack on Israel, Mackenzie Watson – dubbed “MackNazi” by many of his neighbors  — has waged a one-man war on anyone posting hostage flyers or removing pro-Palestine stickers, according to court records and some of his alleged victims.

“He really just hates Jews,” said a 48-year-old resident who’s watched Watson’s antics and estimated at least 100 Upper West Siders “have had bad run-ins with him.”

She also said Watson — who lives in the nabe with his 29-year-old sister Jamie Linn Watson, who’s appeared in FX’s “What We Do in the Shadows” and the Judd Apatow flick “Please Don’t Destroy: The Treasure of Foggy” — seems more worried about ripping down posters than caring for the pooches he walks.

“He’ll sometimes have four dogs; they’re hooked to his waist, and he’s using both hands at the same time to just pull off the stickers at every corner,” the woman added.

Watson’s most recent outbursts include a June incident where he tailed and harassed a 15-year-old girl and her mom, 56, after the teen ripped off one his “antisemitic” stop-genocide stickers from a lamp post on the corner of West 103rd Street and West End Avenue, the fearful mother recalled.

Watson then shoved his phone camera in their faces before stalking them for five blocks as they tried to flee him, she said.

“I don’t give a s–t about the hostages, and I don’t give a shit about the thousands of dead babies,” the mom recalled Watson screaming. “F–k you, piece of s–t! Go f–k yourself! Eat s–t, Zionists! Go kill yourself!”

The mother later that day went to the NYPD’s 24th Precinct to file a complaint against Watson, only to run into Gary Paul — another neighbor doing the same thing.

Paul, a 71-year-old architect, told The Post he’s had multiple hostile encounters with Watson over the stickers and signage — at least two of which drove the anti-Israel maniac to follow him multiple blocks.

“It’s not safe for us,”said Paul.

In April, Watson sadistically stuck his phone camera in the face of a 45-year-old woman posting stickers raising awareness of Israeli and American hostages taken captive by Hamas — and screamed in her face “Zionist bitch! Zionist c—t!”

The woman said she now carries pepper spray in case she ever runs into him again.

“I shouldn’t have to live this way,” she said.

In November 2023, he shoved Joseph Goodrich, 32, to the ground, punched him and dislocated his shoulder — after Goodrich tried to stop the anti-Israel radical from tearing down hostage posters, according to a criminal complaint and the victim’s lawyer, Peter Gordon.

Watson was charged with assault, but soft-on-crime Manhattan District Attorney Alvin Bragg’s office gave him a slap on the wrist, allowing him in June to plea bargain to a conditional discharge on a lesser charge of second-degree harassment if Watson completed anger management courses and kept out of trouble for a year.

Less than two months later, Watson violated the plea deal by being arrested and charged with allegedly clawing the face and kicking the shin of a 59-year-old man, who intervened in a squabble between him and a woman who objected to the dog walker tearing down a hostage poster on Broadway and West 100th Street, according to the NYPD and a criminal complaint. 

The DA’s office charged Watson with assault and harassment and requested a judge void the conditional discharge in the initial assault case, according to court records.

At his home on Friday, Watson would only say “there’s a genocide going on” and “that’s what we should be concerned about” before shutting the door on a reporter.

Watson is among the latest in a long list of New Yorkers who’ve come under fire since Hamas’ terror attack 14 months ago for tearing down Israeli hostage posters and similar signage, including an Adam administration staffer whose job includes bridging “cultural divides.”

After The Post’s expose last week on Nallah Sutherland — who initially was only required to take multicultural training classes and had a disciplinary note put in her work file — Mayor Eric Adams intervened and indefinitely suspended her without pay.
