Amy Gutmann, president of the University of Pennsylvania, spoke with HuffPost Live at Davos on Friday about freedom of speech.
"The challenge of free speech is when there's speech you really don't like," Gutmann said. "We have to live up to the challenge and stand by free speech when it's offensive speech, as well as when it's speech we like."
Gutmann said offensive free speech fosters more discussion, which can be a good thing.
"The creative spirit comes alive when you can robustly argue with people and feel protected, and feel safe," she said.
"When the speech is offensive I feel we have a responsibility to respond," Gutmann added.
