The whole responsibility of a rape is on the rapist!
Nothing a victim does causes them to be raped. It makes me angry, sad and concerned to name a few when you hear of people having to adjust their behaviour to keep themselves safe.
Also is the fact that no always means no. If someone does not have the ability to say no then the answer is still no. Silence should never be taken for consent. Surely these are things people should be taught at a young age!
