Yes it was. 

From wiki:

"In late 2015, Yiannopoulos began a campus speaking tour called "The Dangerous F*ggot Tour", encompassing universities in the United States and Great Britain. A number of his scheduled speeches in Great Britain were cancelled. Although most of his American speeches were not cancelled, some were met with notable protest ranging from vocal disruptions to cancellation via the heckler's veto. The journalist Audrey Goddard analysed his speech at the University of Pittsburgh. He concludes that Yiannopoulos spends the "majority of the time voicing his opinions with little to no factual statements accompanying them."

It should be noted that Yiannopoulos is a self-hating gay person who pines for conversion therapy but will say anything for a buck.
