Picture this: You're poor, you don't have a car, you work as a server where your uniform has a short skirt, you get off work after the buses stop running in your municipality. How completely unwise of you. You should have had more money and bought a car. You should be able to afford to live in a better area. You should be able to get a better paying job. It's all your fault if you get raped walking home.

That's what they mean by unavoidable circumstances, and by victim blaming.
