Seconded.
I can't believe this is so difficult for some people to understand.
One word: context.
Had the girl been hit by a drunk driver, everyone would've been outraged at the drunk driver. They wouldn't have started looking for things she could've done differently or scolded her for drinking too much or not crossing the road away from a zebra crossing or for wearing dark clothing or for reezing when she saw the speeding car bearing down on her instead of trying to jump away; they would've been furious at the drunk driver.
If I understand the parallel, you are saying that Williams was not furious at the rapists? That she supports rape somehow or other?
I hope you get that one can be both mad at the rapist and still advise caution so that others don't put themselves in risky situations? Wouldn't you support any advice from a celebrity that helped prevent the next rape?
