Rebecca Solnit's article, Our Words Are Our Weapons: The Feminist Battle of the Story in the Wake of the Isla Vista Massacre, has been reprinted widely on internet sites. I think I first encountered it on Slate -- or maybe Salon. Where, predictably, the vast majority of comments were howls of outrage by men -- personal attacks upon her intelligence and accusations of man hating, rather than any reasoned response to her reasoning.
Rebecca Solnit has had the most reasoned responses to the Santa Barbara killings, or so it seems to me. But she doesn't connect all the dots in this matrix of domestic terrorism that include gun possession and entertainment that 24/7 invades our homes, workplaces and even billboards that show in graphic detail women being humiliated and otherwise violated for the fun of it. Or to sell consumption of everything from beer to chainsaws. Or to be awards provided for being the most violent of all in any fictional simulacrum of combat, including sports.
However, it's hard to see Our Words as effective means when so many men refuse to read them, listen to them or even understand what the words mean.
