A disturbing confessional video uploaded to YouTube by the man authorities believe killed six people in Santa Barbara, Calif., Friday has many around the web expressing a mixture of shock, pity and outrage toward 22-year-old Elliot Rodger this weekend.

In the video, Rodgers said, "You girls have never been attracted to me. I don't know why you've never been attracted to me, but I'll punish you all for it. It's an injustice — a crime."

"I don't know what you don't see in me," he continued. "I'm the perfect guy, yet you throw yourself at all these obnoxious men instead of me, a supreme gentleman ... If I can't have you, girls, I will destroy you. You denied me a happy life, and in turn I will deny you a life."

As Rodgers' video confessional spread online Saturday, many took to Twitter to speak out against the chilling misogynistic attitude Rodger appears to convey in his confessional.

Using the hashtag #YesAllWomen, thousands have responded to Rodger — who reportedly frequented controversial "men's rights" web forums — and others online who claim misogyny is not a big problem. People have come forward with their own experiences of sexist violence and harassment, as well as those of their sisters, mothers, daughters and girlfriends.

To date, the hashtag has been used more than 455,000 times on Twitter and continues to trend in the United States and Canada.

People in Calgary and Edmonton have been sharing their stories of misogynistic violence as well.
