While I agree that prevention is important but still it doesn't mean the victim should be blamed. She should learn and practice more precautions in future definitely but it's not her fault for being raped.

She agreed to have sex with 1 guy only and not the whole group. Regardless she was drunk or not, the person who received the invitation should not have invited his friends to tag along without her consent.

Based on the earlier analogy it's different. Rempit snatch your bag is rempit fault, you put your bag on your car boot while talking on the phone then someone snatch it away, still the snatch theif fault mainly but you can't say that you yourself completely not to be blamed right? But this has nothing to do with the rape case la, just comaparing his locked and unlocked house analogy.
