I think that even dismissing someone like J Dickinson is really unfortunate because it's always easy to dismiss the eccentric party girl. Well, prostitutes can be raped and women of every age, race and personality; just because J Dickinson is part of Hollywood culture doesn't make it less likely. As a matter of fact, predators may choose carefully a "broken bird" because it makes the perpetrator that much more believable and makes it easier to claim "well she's crazy"...
For example, one of my close friends was raped by another student at our high school. She was an outspoken girl, sometimes a drama queen, and many of her friends stopped being her friend because she spoke out. It got pretty heated at school and people tried to silence her. Some kids didn't want to deal with it and the perpetrator kept lying saying she was just crazy. A few of us believed her and were really upset that nothing happened to the student and it was downplayed. Well, eventually the perpetrator admitted that he raped her after he wasn't going to get in trouble. Initially they thought she was being "dramatic". The point is, is it's not about personalities, it's about facts. To me, it does women a disservice to take their claims less seriously because they are in limelight or in a non-traditional female profession.
ETA It's just appalling that Cosby "spanish fly" comedy bit was allowed and that people actually found it funny. Sometimes the misogyny is too much. BC actually discussed with L.King awhile ago:

If BC can joke about it, he probably confided in his friends or acquaintances what he was doing (if allegations are true). If so, I bet there are male friends of his that are fully aware of his crimes, and hope they speak out if that's the case.
