Brooklyn Borough President Eric Adams gave a bizarre and incendiary rant at the opening of a new senior center for poor and LGBT New Yorkers on land owned by the city’s Housing Authority — implying there could be confrontations between longtime residents and new tenants.

“I can’t celebrate a building that is not going to be inclusive. That is not who I am. Those who know me, they know who I am. And I’m unapologetic about who I am,” Adams said at the Dec. 17 event celebrating the opening of the building.

“Because if you have a body of people over there that feels as though this place here is not for them — we’re going to have incidents in this community that will be disruptive. And I don’t want that to happen,” he continued, in a recording obtained by The Post. “I didn’t put on a vest for 22 years to protect the children and families of this city to watch us be divided.”

It’s not clear exactly what the 2021 mayoral hopeful meant when he claimed the new Stonewall House building at Fort Greene’s Ingersoll Houses is not inclusive.

More than three-quarters — 77 percent — of the new residents are African American, Latino or Asian. Each tenant in the new building is at least 62 years old and makes less than $40,000 a year. More than a third of the building’s new apartments will be filled by NYCHA tenants — a quarter of its 145 units are reserved for once-homeless New Yorkers.

Adams made the remarks as part of a three-minute address to project boosters, including top officials for city agencies, the project’s developer, and the LBGT charity that will operate the building — the bulk of whom were white.

The top official at the city’s Human Resources Administration, Grace Bonilla, followed Adams and fired back in her speech, telling the crowd: “I can’t follow the Borough President without addressing what he had to say.”

“Our hope is that every single client has a place like this to live in, to actually talk to the people that are going to get a key and say ‘you no longer have to be homeless,’” Bonilla said.

“So, I echo what the Borough President said, we do have more to do, but I do want to celebrate today because today is an accomplishment,” she later said.

Audience members told the paper they were shocked and disturbed by the “completely absurd” remarks at the ribbon-cutting ceremony.

“I thought it was out of line,” said one person who attended the ribbon-cutting. “Everybody there was in a celebratory mood.”

“I was really disturbed by how he acted here,” the attendee added.

Adams, a former NYPD cop, later referenced how the new building has nicer facilities than the Ingersoll Houses, which opened in 1944.

“I don’t want to see beautiful floors like this and lead paint over there. I don’t want to see rodents over there and comfort here. Thank you,” he said, concluding his short speech.

Another person close to the project said people were “taken aback” by the bizarre rant.

“This was a project we’ve all been working on for several years,” the person said. “None of the facts support his stance.”

“I would say it was reckless if it wasn’t on its face completely absurd,” they added. “It’s a cynical vote-grabbing ploy.”

Adams tried to walk back the comments when reached by The Post on Wednesday, claiming his “honest and passionate” remarks came after several community members voiced their concerns about gentrification.

“I want to be loud and clear that new construction in our community must reflect the diversity of the longtime black and brown residents that are being displaced at an alarming rate, and that those who live and pay rent in public housing cannot live in a second-class existence,” he said.

An Adams spokesman later said that the “Borough President is in no way endorsing or trying to incite any form of violence.”

“I think any suggestion of that is completely belied by his staunch support and his record on public safety throughout his career,” the rep, Jonah Allon, added.
