I think people are pretending to misunderstand the theft analogy. No-one is saying that doing things in the hopes of reducing rape risk means that rape is the same as theft, or that vaginas need to be locked up. They are saying that in the abstract, doing things that might reduce the chances of a crime happening to you are sensible things to do, but that it doesn't mean that it's your fault if that thing does happen. Likewise, avoiding unlit places, being too drunk to know what's happening, staying with friends, etc, are sensible precautions to keep you safe. it doesn't mean it's your fault if someone rapes you. Lots of black and white thinking happening, too. Most rapes aren't carried out by random strangers. So why does that mean we shouldn't still try to prevent those few that are? Men should be the ones who are educated not to rape. Agreed. By why not also take precautions yourself against some of the risks? You can't prevent rape unless you never go out. Again, agreed. But there are sensible things that might reduce the risk slightly, and being careful when drunk, staying in a group, etc might help. It doesn't have to be either/or.
And I still wouldn't have automatically assumed that the poster was anything to do with rape, if I saw it. More to do with train/rail/track safety, high heels, floating clothing, drunk escapades, stairs, train/platform gaps, etc etc. Maybe they are targetting women because that's who's been having the problems lately, that's who's been injured, that's who's been so drunk they can't remember their address, whatever. Maybe it's because it's a newer problem. It just doesn't automatically make me think 'victim blaming' and 'rape warning' when I read it.
