The unhinged Manhattan college professor who went viral for cursing out anti-abortion students shockingly held a machete to a Post reporter’s neck Tuesday — and made wild threats she was going to “chop” him up.

Shellyne Rodriguez spewed the menacing remarks when The Post knocked on the door of her Bronx apartment Tuesday morning — a day after she made headlines for flipping out on pro-life students at Hunter College.

“Get the f–k away from my door, or I’m gonna chop you up with this machete!” the manic adjunct art professor shouted from behind her closed door just moments after veteran reporter Reuven Fenton identified himself.

Seconds later, Rodriguez barged out and alarmingly put the blade to the reporter’s neck.

“Get the f–k away from my door! Get the f–k away from my door!” she raged before retreating back into her apartment and slamming the door.

The Post reporter and photographer immediately left the apartment building, but an armed Rodriguez quickly followed and accosted them outside.

“If I see you on this block one more f–king time, you’re gonna … ” Rodriguez said, while still wielding the knife.

“Get the f–k off the block! Get the f–k out of here, yo!”

The professor briefly chased The Post’s photographer down the street to his car before coming back to kick the reporter in the shins.

She finally retreated into her building just moments later.

The terrifying ordeal unfolded after footage surfaced online that showed Rodriguez unleashing a profanity-laden attack on anti-abortion students who’d set up an information table at Hunter College earlier this month.

“You’re not educating s–t. This is f–king propaganda,” the art professor hissed to the students in the May 2 incident. “What are you going to do, like, anti-trans next?”

A male student behind the table was filmed telling her, “I mean, no, we’re talking about abortion” and that he was sorry about “triggering” her students.

Rodriguez fired back, telling the male student he couldn’t be sorry “because you can’t even have a f–king baby.”

The video, which was posted to Twitter by Students for Life of America, then showed the professor tossing the students’ pamphlets.

It wasn’t immediately clear what unfolded between Rodriguez and the pro-life students before the camera started rolling.

A rep for Hunter College, a public school that is part of the city’s CUNY program, has said the school is aware of the caught-on-camera altercation and “taking this matter very seriously.

“The provost has opened an investigation into the professor’s actions,” the representative said.

The college did not immediately return a request for comment from The Post about the attack on its reporter and photographer.
