The John Jay College professor who said it’s “a privilege to teach future dead cops” has at least one fan — Dartmouth College visiting scholar Mark Bray — who’s now also come under fire from police.

Mike Isaacson, who went into hiding after posting the offensive tweet, shouted out Bray on Twitter early Saturday morning for signing a copy of his book, Antifa: The Anti-Fascist Handbook.

In the post, Isaacson writes “My parents got me @Mark_Bray’s book. He’s such a sweetie” and includes a photo of the book with an inscription from Bray attacking Isaacson’s critics.

“Don’t let the bastards grind you down,” Bray’s handwritten message reads.

Isaacson, a self-proclaimed member of the Antifa movement who goes by the Twitter handle @VulgarEconomics, drew widespread condemnation for his Aug. 23 tweet about the law enforcement officers he’s supposed to teach at the CUNY college.

He was put on leave after posting the Tweet. He didn’t immediately return a call seeking comment on his latest posting.

Bray, who’s Dartmouth bio describes him as a “historian of human rights, terrorism, and political radicalism in Modern Europe,” came under fire Sunday for his support of Isaacson.

“People like Bray and the other guy really don’t have a place in academia,” said Ed Mullins, president of the Sergeants Benevolent Association. “They’re riling up people to cause public harm.”

Bray’s support of Isaacson should give Dartmouth pause, said Mullins, who added that deep-pocketed donors should consider withdrawing funding from endowments if colleges fail to offer countervailing opinions.

“If academia wants to continue to approve of this, maybe people need to rethink where they’re putting their money,” he said.
