That's an argument that would work if the harassment and SA was about attraction or wanting something they were being denied.
Being unconventional looking can sometimes be the very reason that a woman gets chosen by a predator, because what they want is to avoid accountability. They know exactly what they're doing when they choose the disabled, the fat, the old, etc. They know no one is going to believe the victim because of the idea that only "pretty" girls get victimized.
Pretty women need ot understand that being considered "ugly" will not save a woman from being preyed upon. In fact they may be chosen for just that reason.
