Ugh. Oprah and Tyra might want to schedule a few more “teachable moments.” The Boston Herald reports that a recent survey by the Boston Public Heath Commission found that almost half of the 200 teenagers surveyed thought Rihanna was responsible for her alleged beating at the hands of Chris Brown. Among the other depressing results: Only 51 percent thought Brown was responsible for the incident, 44 percent thought that fighting was a normal part of a relationship, and a “significant number said ‘Rihanna was destroying Chris Brown’s career.'” For years public heath advocates have been trying to flip the narrative on domestic violence: That it isn’t like other relationship issues, that it’s not something that can be worked out, that it’s the ultimate, absolute, never-look-back deal-breaker. But now, as one anti-violence advocate said in the Herald piece, “Somehow young people have gotten the message that this is just part of a relationship.” This news, coupled with People.com’s report that Rihanna and Brown have recorded a “sweet and sentimental” duet, leaves me more than a little depressed this morning. What do you think PopWatchers? Is this survey just a blip? Or has the Chris Brown and Rihanna saga seriously damaged the fight against domestic violence?
