Sick power mad men are the underlying cause.
A burglar rapes a 95 years old lady in her home.
A young man is dragged into an alley and infected with aids.
It has nothing to do with underwear.
As for screaming - My mother was once grabbed on the way home from work (1955) and dragged into an alley. The man put his hands around her throat. She said that it was such a shock that her legs went weak, and she could hardly even croak. It was only as he started groping that she realised her life was in danger and she said "leave me alone or I shall scream and not stop." When she started screaming (Mom had a loud voice) he ran away.
But what about those girls who don't have the strong character? My Mother never agreed with the scream/don't scream thing in all her years with the witlessness because of her own experience. It is never the victims fault.
