They’re parading straight into custody.

Anti-Israel protesters tried to ruin the Macy’s Thanksgiving Day Parade for the second year running Thursday, with cops quickly swarming in to gobble up roughly 25 arrests.

The firebrands entered the parade route at West 55th Street and Fifth Avenue, stopping the Ronald McDonald balloon in its tracks around 9:25 a.m., police said — and drawing loud jeers from parade-goers screaming at the killjoys to move.

Photos showed protesters sitting in the parade’s path, with some unfurling a large banner that read: “Don’t celebrate genocide!”

“Get the hell out of here,” a parade-goer yelled amid a chorus of boos from the crowd, which seemed more interested in the Bluey balloon’s arrival than the plight of Palestinians in Gaza.

NYPD officers quickly descended upon the group, who shouted “Free, free Palestine!” as they were tackled to the ground and placed in handcuffs.

Cops cuffed about 25 protesters “without incident” and hauled them away to face pending charges, police said – but the arrests appeared more violent than the NYPD’s account.

Some unruly protesters could be seen being forcibly pried away and flipped over onto their stomachs to be handcuffed. Footage captured by The Post showed the protesters holding the banner scuffling with cops before they too were thrown onto the ground and handcuffed on top of their crumpled-up sign. 

Other demonstrators willingly stood up and walked with police away from the parade. 

The rabble rousers were carted to One Police Plaza, where they spent hours during their Turkey Day in the NYPD’s mass arrest processing center, sources said.

”This is disgusting,” said a Brooklyn cop. “There are times and places to peacefully protest, but not the Thanksgiving day parade. This a day for families to enjoy and not be interrupted by these a–holes.”

The protesters were “autonomous anti-genocide activists,” independent reporter Talia Jane posted on X, along with a viral video viewed 1 million times showing them hop barricades, block the Ronald McDonald balloon and sit in the street.

Their antics only disrupted the parade for about five minutes.

Mayor Eric Adams had already warned protesters not to dare repeat last year’s disgrace, where many glued their hands to the parade route.

“I really want to take the moment to tell those grinches that believe they are going to disrupt the parade that it is not going to happen,” Adams said Wednesday night ahead of the iconic parade.

The protests during the parade Thursday appeared less disruptive than last year’s, when officials said cops arrested about 40 agitators.

Two people waiting outside NYPD headquarters for protesters to be processed declined to comment to The Post.

City Hall spokeswoman Kayla Mamelak called this year’s disruption “disrespectful.” 

“Interrupting New York City’s Thanksgiving Day Parade to protest a conflict overseas is disrespectful and accomplishes absolutely nothing,” she said.

“They have won over no one, and, instead, have just disrupted a fun day for thousands.”

But protesters didn’t confine their antics to the parade.

Pranksters hung banners from the Queensboro Bridge decrying “genocide” and blaring “Free Palestine, free the land, free them all.”

The banners were as much a pro-Palestinian message as an anti-Thanksgiving one, according to a “communique” apparently from the protesters posted by Jane, the independent reporter.

“On the holiday where this fascist empire commemorates its first but not only genocide, a group of autonomous organizers remind us that fascism here or anywhere is linked to genocide here and everywhere,” it read. “The only solution is global Intifada. LAND BACK NOW.”
