This is a bit out of date - it is from 2014 - but I thought it was extremely interesting and largely unreported at that the time.
Feminist pop culture critic Anita Sarkeesian was forced to cancel a talk at Utah State University, after a threat of a massacre if she was allowed to speak about the portrayal of women in video games in October 2014.
A vile threat was sent to the school in an unsigned email. Sarkeesian wanted to go ahead with talk anyway, but was told that permissive gun laws made it impossible:
Initially, Sarkeesian stated her intention to hold the talk despite the threat, but was forced to back down after discovering that it was impossible to prevent guns being taken to the event.
“Forced to cancel my talk at USU after receiving death threats because police wouldn’t take steps to prevent concealed firearms at the event,” she tweeted. “Requested pat downs or metal detectors after mass shooting threat but because of Utah’s open carry laws police wouldn’t do firearm searches.”
The school confirmed Sarkeesian’s explanation in a statement. “During the discussion, Sarkeesian asked if weapons will be permitted at the speaking venue. Sarkeesian was informed that, in accordance with the State of Utah law regarding the carrying of firearms, if a person has a valid concealed firearm permit and is carrying a weapon, they are permitted to have it at the venue.”
The author of the threatening email wrote that if the talk was not cancelled, they would carry out an attack in the style of the 1989 Montreal massacre, when Marc Lépine murdered 14 women, claiming he was “fighting feminism”.
“I have at my disposal a semi-automatic rifle, multiple pistols, and a collection of pipe bombs,” the letter said. “This will be the deadliest school shooting in American history and I’m giving you a chance to stop it.”
“You have 24 hours to cancel Sarkeesian’s talk … Anita Sarkeesian is everything wrong with the feminist woman, and she is going to die screaming like the craven little whore that she is if you let her come to USU. I will write my manifesto in her spilled blood, and you will all bear witness to what feminist lies and poison have done to the men of America.”
