Video surfaced on Thursday showing Michael Mulgrew, president of New York’s United Federation of Teachers, as he unloaded a hateful rant against critics of the Common Core Standards Initiative.

“If someone takes something from me, I’m going to grab it right back out of their cold, twisted, sick hands and say it is mine!” Mulgrew bellowed clownishly. “You do not take what is mine!”

The union boss also challenged opponents of Common Core and union control over education to a fist fight.

“I’m going to punch you in the face and push you in the dirt because this is the teachers’!” Mulgrew threatened.

The teachers union bigwig made the speech at a convention in Los Angeles last month, according to the New York Daily News.

Ed Notes Online, a blog that follows education news, posted the screed yesterday.

Mulgrew’s bizarro, menacing outburst was part of an intense debate on a mundane resolution calling on the 1.4 million-member American Federation of Teachers to continue its support the implementation of Common Core.

“I’ve heard the stories about how Eli Broad, Bill Gates, Joel Klein and a flying saucer full of Martians designed these things to brainwash us all,” Mulgrew also raged in scorn of the growing grassroots tide of opposition to Common Core.

Attendees at the convention said the hulking, bald and very angry union boss’s intimidating diatribe was frightening.

“It was scary,” a member of the audience who wished to remain anonymous told the Daily News. “People were saying that he shouldn’t be around children.”

Across the country, bureaucrats in 45 states, Washington, D.C., and four U.S. territories had originally decided to implement Common Core with virtually no democratic input.

Since then, a handful of states have either neutered or — in the case of Oklahoma — banned Common Core entirely. Legislatures in several more states are mulling bills that would limit the controversial national standards.
