“A substantial” number of Gen Z voters supporting socialist NYC mayoral frontrunner Zohran Mamdani have been brainwashed by leftist ideology into an army of “nasty,” USA-hating radicals — who routinely accost rival Mayor Eric Adams on the campaign trail, Hizzoner revealed to The Post.

“I have never witnessed a more mean and angry and nasty electoral season — and not all of Zohran’s voters are, but a substantial number of them,” Adams said during an exclusive 20-minute sitdown at Gracie Mansion.

“You know, when you sit in a restaurant with a family, a family restaurant, children are there, and you’re sitting down with your loved ones and family, and someone is yelling out, ‘F you!’ Cursing!

“Or walking into a church, a synagogue, and someone is just cursing and yelling … That has never been like this before in the city … People are ‘F U Adams! F you!’ … When you do it in front of children, it says to me you have no regard for the civility that’s associated with living in a city of this magnitude.”

Hizzoner blamed left-infested public schools, colleges and other institutions for indoctrinating impressionable youth, creating a veritable Red Army.

“Our children are being radicalized, and no one wants to talk about it, but I will, because I see it,” said Adams.

“I see how our children are starting to hate their city, to hate our country, and that is something that we must address.

“A lot of young people are going on, doing great things, going to school —  but a substantial pocket of our young people have been radicalized in the city through a number of means: our school campuses, through social media, through their peer groups. The radicalization is real.” he added.

The moderate Democrat said the problem isn’t limited to New York, citing the Sept. 10 assass!nat!on of conservative pundit Charlie Kirk in Utah, and last month’s slaughter at a Minnesota church by Robin Westman, who confessed that he “was tired of being trans” and wished he “never brain-washed” himself.

“You don’t have a 22-year-old assass!nat3 someone because you disagree with them,” he said. “You don’t have a young person going into a Catholic school shooting children … I’m not sure what it’s going to take for us to realize that … ‘Houston, we have a problem.’”

Support from younger voters played a pivotal role in Mamdani’s stunning upset over ex-Gov. Andrew Cuomo in the Democrat primary. Cuomo, like Adams, is now running for mayor in the Nov. 4 general election as an independent.

Mamdani has support from 64% of “likely” New York City voters ages 18 through 29, compared to 14% for Cuomo, 11% for Republican nominee Curtis Sliwa, 9% for Adams, according to a Marist University poll released Tuesday.
