Replying to Rape vs Theft Double Standard

Why do people accept that thieves exist, and victim blame when the victim does something obviously stupid and gets robbed. But when a rape occurs, it is egregiously wrong to question the actions of the victim leading up to the incident?

Im not equating the severity of the injury to the victim, i am comparing how society reacts totally different to victims of two crimes in which the victim is equally at fault in both(not at fault).
