Ann Coulter's canceled speech at the University of California-Berkeley is just another example of the far left's assault on free speech, Sean Hannity said in his opening monologue tonight.

"They want to silence every single conservative voice in America," Hannity said, explaining that "out-of-control fascists" are stifling any speech that dares to challenge their politically correct worldview.

"What happened in Berkeley should trouble every single one of you, the American people," Hannity said. "College campuses in this country are no longer environments for learning and robust debate and the free and open exchange of ideas. And they haven't been for a long time."

He argued that rational thinking has been replaced on campuses by "safe spaces" and "microaggressions."

Hannity pointed out that all Coulter was going to do at Berkeley was give a speech about how the U.S. should actually enforce federal immigration laws.

"If you don't subscribe to the rigid, left-wing ideology that's being pushed by the so-called 'tolerant' alt-radical left, you're going to be shut down and you'll be silenced by any means necessary," Hannity said.

"I urge you all tonight: Make your voice known. This madness has to stop."
