John Jay professor who tweeted about dead cops gets hate mail

The John Jay College professo𓂃r who said it is a “privilege to teach future dead cops” is — surprise, surprise — getting a lot of hate mail.

Mike Isaacson was put on leave from the famous Manhattan school for criminal justice after his Aug. 23 tweet about the very l🧜aw-enforcers he is supposed to help train.

Isaacson, a self-proclaimed member of the Antifa movement who teaches economics and whose handle is @VulgarEconomics, began posting a “thread of some of the threats I’ve received” Sunday after he made an appearance on TV’s “Fox News” the day before.

The threats ranged from violent 🍒and epithet-laden to tamer jibes ab๊out his wild hair.

“First of all the Tears for Fears haircut has got to go,” @ThunderRikki wrote in a Twitter direct mes⛎sage that

“I’m challenging you right now asshole,” the missive continued. “Tell me where you live and I guarantee I will bloꦜody you so bad no one will recognize you.”

, “@VulgarEconomics I was a cop till I got injured. I know where your col♐lege is. I am a great shot! What do we want, we want dead professors.”

One scre🎶enshot of an e-mail included the name, phone number, and Manhattan address of sender Marco Praderio, “the real fascist,” and a “putrid and cancerous worm who should be sent as a gift to ISIS.”

Praderio told The Post on Sunday that he is now concerned that Isaacson bro❀adcast his personal information and said he will know who to blame if he started receiving threats himself.

“I h🍃aven’t received anything from anybody, but if I get harassed by these violent fascistic pieces of ꧙dirt I will swipe back at him,” he said.

The head of the police union has called for Isaacson’s firing, and Mayor de Blasio condemned the professor , writing “New York City won’t stand for the vile anti-police rhetoric of Michael Isaacson and neither should John Jay College.”

Isaacson༒ did not respond to a message seeking commenꦐt Sunday.
