Attitudes like the above are harmful and I don't believe they should ever be encouraged. Blame the people taking advantage of the other person, not the victim.
I agree. But as the author suggests, the question then becomes a matter of the extent of punishment, and how to deal with the vagaries involved. The author herself describes a situation where she pressured someone into sex. Based on her own admission, there is little doubt that the man was a victim there, but to what extent should she be punished, and what constitutes adequate evidence before punishment should be applied?
I personally know of a teacher that was accused of sexual assault. The teacher lost his job, and it was only later that the accusers admitted that they fabricated the assaults as revenge for an academic issue. The school was very quick to dismiss the teacher, and it's difficult to blame them, given that schools have a powerful motivation to avoid lawsuits, they often aren't impartial judges in such matters.
Personally, I think the author here is focusing too much on the nature of these policies, and not enough on the motivations behind them. IMO failings in these policies reflect that they originate in institutions that are often liable for damages in cases of assault. For that reason, they aren't structured primarily to protect the victim, but to legally protect the insititution. These are crimes, and law enforcement is charged to serve and protect. As you cite, they are failing miserably here, and unfortunately, there is plenty of reason to believe that they aren't currently up to the task either. Still, that doesn't mean that it isn't their duty to address it.
