Sarkeesian has canceled a speech at Utah State University after learning the school would allow concealed firearms despite an anonymous threat against her. Sarkeesian was scheduled to give a presentation on the portrayal of women in video games Wednesday, Oct. 15, 2014. She decided to cancel Tuesday after the university received an anonymous threat from a person who threatened to carry out a mass shooting if the event was held. Sarkeesian pulled out after learning from university officials that concealed weapons would be permitted, as long as attendees have a valid concealed firearm permit in accordance with Utah law.
