The John Jay College professor 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 law-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 about his wild hair.
“First of all the Tears for Fears haircut has got to go,” @ThunderRikki wrote in a Twitter direct message that Isaacson screen-shotted and tweeted out.
“I’m challenging you right now asshole,” the missive continued. “Tell me where you live and I guarantee I will bloody you so bad no one will recognize you.”
User @nj335xi posted, “@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.”
One screenshot of an e-mail included the name, phone number, and Manhattan address of sender Marco Praderio, who called Isaacson “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 broadcast his personal information and said he will know who to blame if he started receiving threats himself.
“I haven’t received anything from anybody, but if I get harassed by these violent fascistic pieces of dirt 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 on Twitter on Friday, 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 comment Sunday.
