A conservative author invited to speak at a California college had her forum cut short due to dozens of angry protesters.
Heather Mac Donald, author of "The War on Cops," said on "The O'Reilly Factor" that before she arrived at Claremont McKenna College to speak, chanting and protests already reached a "hysterical level."
She said it brought to mind the kind of a scene that a person bound for the guillotine during the French Revolution might witness.
Mac Donald said that there were police at the venue to protect her, but that students were able to break through and get closer to the building in what she called "feckless crowd control."
Mac Donald said she was called a "white supremacist fascist" and added that the protesters' actions were ironic, since they considered themselves anti-fascist.
She asked whether the students would excuse conservatives protesting and shutting down a speech by left-wing Sen. Elizabeth Warren (D-Mass.) in the same way.
"They are not allowing fellow students to hear a range of views," she said.
