The rampage near the campus of University of California, Santa Barbara, has sparked debate about attitudes toward women and violence. The response comes after suspected gunman Elliot Rodger, who killed himself, revealed in a manifesto that the assault was retaliation against women for starving him of affection. Such attitudes represent examples of men feeling entitled to threaten women, said some students on campus, where a gang rape this year had also heightened fears. On social media, thousands have begun discussing violence against women under the hashtag #yesallwomen. The attack claimed seven lives, including Rodger’s.
