Shortly after the 2017 Las Vegas shooting, Ciccariello-Maher posted tweets saying the mass shooting in Las Vegas, which left 59 people dead and hundreds injured, was the product of a system that favors white males. His statements, such as "It's the white supremacist patriarchy, stupid", resulted in a number of death threats. Subsequently, he wrote an op-ed for "The Washington Post" in which he elaborated on his tweets, stating "I tweeted before then diagnosing a sense of double entitlement—as white people and as men—that, when frustrated, can occasionally lead to violent consequences."
