A California man has killed seven people including himself after posting a video to YouTube saying he was seeking retribution against all women for rejecting his sexual advances. Elliot Rodger stabbed three people to death at his apartment Friday before driving to a sorority house at the University of California, Santa Barbara, where he killed two women outside. He drove through town continuing to fire on pedestrians, before dying of what authorities called a self-inflicted gunshot wound. Hours before the attack, Rodger posted a chilling video saying he planned to attack “you girls” for what he called the “crime” of not being attracted to him.

Elliot Rodger: “On the day of retribution, I am going to enter the hottest sorority house of UCSB, and I will slaughter every single spoiled, stuck-up blonde slut I see inside there.”

Rodger’s misogynist comments sparked a viral response on Twitter, with more than a million tweets using the hashtag #YesAllWomen, seeking to put the attack within a wider context of everyday harassment and violence. Among those killed in the massacre was 20-year-old Christopher Michaels-Martinez, whose father has reignited the call for gun control.

Richard Martinez: “Why did Chris die? Chris died because of craven, irresponsible politicians and the NRA [National Rifle Association]. They talk about gun rights. What about Chris’s right to live? When will this insanity stop? When will enough people say, 'Stop this madness! We don't have to live like this”? Too many have died. We should say to ourselves, 'Not one more!'”
