Princeton professor and former chairman of the United States Commission on International Religious Freedom took to social media to denounce the cancellation.
"When speaking events are cancelled under threats of violence, there is no free speech. The mob has been given censorial powers. We all lose," tweeted George, getting as of Thursday afternoon more than 750 likes and over 400 retweets.
George also tweeted: "Cancelling a speech under the threat of violence was wrong. It was the duty of the university & city to provide security. No heckler's veto!"
