The John Jay College professor who said it is a “privilege to teach future dead cops” has gone into hiding amid an avalanche of death threats.

Mike Isaacson told The Post on Sunday that he fled the city — and refused to reveal his whereabouts — after his offensive Aug. 23 tweet.

“I was not really considering that people would take this seriously,’’ said the clueless adjunct economics teacher, who was put on paid leave from the Manhattan CUNY school of criminal justice.

But he was unrepentant.

“The content of the tweet is a fact, because I teach police and everybody dies, including police,’’ he said.

Isaacson, a self-proclaimed member of the antifa movement whose handle is @VulgarEconomics, on Sunday posted a “thread of some of the threats I’ve received” after he made an appearance on “Fox News’’ the day before.

“@VulgarEconomics I was a cop till I got injured. I know where your college is. I am a great shot! What do we want, we want dead professors,” user @nj335xi wrote.

Isaac also posted a screenshot of an e-mail from a George Freeman that raged, “You’re a little f–got k-ke, rope yourself you f–king Jewish subverter.”
