CHICAGO – Over 100 students protested at DePaul University Wednesday night over a speech by a right-wing author.

Charles Murray, a conservative author with controversial views on education, gave a speech at DePaul and protesters were on campus to speak up against the his visit.

Murray was invited by the DePaul College Republicans. The university said a lot of thought and debate went into the decision to let him speak.

Students who gathered Wednesday night said he’s racist and that their school made the wrong choice.

Student protestors shut down Charles Murray’s speech at the University of Michigan last month. There were fears students at DePaul may take similar actions.

There were protests at his East Coast appearances as well that turned a little violent and back in March about 100 protesters turned out for a Murray speech at Notre Dame.

The message each time is the same cries of junk science and racism.

Murray is a libertarian speaker and author and a member of a D.C. based conservative think tank. Among his more controversial books is one called “Coming Apart: State of White America 1960-2010.”

Another book is called “The Bell Curve,” which examines whether different social and even racial groups may have different levels of intelligence.” He attributes different cognitive abilities to different groups and students at DePaul said that’s not science but racism.

“What Charles Murray represents is not what we’re about here at DePaul. We’re about positive dialogue and he’s pushing a racist agenda that divides and does not bring the community together,” Gisselle Cervantes, a DePaul student, said.

The university debated the request by DePaul College Republicans to hold the event saying in a statement they do not endorse Murray’s views.

Extra police were on hand to make sure everything went as planned.

Full statement from DePaul:

“DePaul does not endorse Mr. Murray’s views. We are committed, however, to the free exchange of ideas through intellectual discussion and dialogue within our educational environment.”

The speech itself was open only to DePaul students and faculty. The university said it was followed by a Q and A session to respect what students wanted–thoughtful debate.
