This puts the standard of conviction much higher than other crimes, because lots of crimes can be committed unknowingly (theft, embezzlement, even homicide), the intent of the criminal having no bearing on their guilt or not. In these cases the experience of the victim bears strongly on the case: the person who's car was stolen, the company who's funds were embezzled or the (deceased) victim of negligent homicide. The speaker is saying that courts do not weight victims' experiences appropriately, if at all, in rape cases.
