“Tolerance” seems to mean something very different these days.

Last night, controversial political scientist Charles Murray took the stage at Middlebury College to speak … and was immediately greeted by a chorus of boos, which soon turned to outright shouting and screaming:

Believe it or not, things got even worse after Murray left the stage:

As [Professor Allison] Stanger, Murray and a college administrator left McCullough Student Center last evening following the event, they were “physically and violently confronted by a group of protestors,” according to Bill Burger, the college’s vice president for communications and marketing.

Burger said college public safety officers managed to get Stanger and Murray into the administrator’s car.

“The protestors then violently set upon the car, rocking it, pounding on it, jumping on and try to prevent it from leaving campus,” he said. “At one point a large traffic sign was thrown in front of the car. Public Safety officers were able, finally, to clear the way to allow the vehicle to leave campus.

“During this confrontation outside McCullough, one of the demonstrators pulled Prof. Stanger’s hair and twisted her neck,” Burger continued. “She was attended to at Porter Hospital later and (on Friday) is wearing a neck brace.”

For what it’s worth, New York Magazine’s Jonathan Chait, a liberal whom you might not expect to denounce campus leftism, is quite disturbed by what happened:
