I didn't handwaive anything. My point is not to argue that the accusations are true or false. My point is that it is terrifying that all it takes is vague accusations + a mob assumption to permanently brand someone as a rapist.
Whether a given instance turns out to be accurate isn't the point. The problem is that we've gone from "not believing women" to "always believing women no matter what," which is the wrong reaction. If the standard is only "some of these accusations are true," or even "most of these accusations are true," how is this different from say, racial profiling by the police?
