Why can't people see the difference between useful advice and victim blaming?
Because rape is such a horrific crime, people will always have intense feelings and it's difficult to think coldly and dispassionately about it.
The burglary analogy is a fair one. There will always be burglars, so I make my house secure. I have good locks and a burglar alarm. It's not a guarantee against burglary, but basic precautions mean that the burglar will usually try somewhere else. The police and insurance companies will confirm this.
Unfortunately there will always be rapists. There shouldn't be, and we all hate the idea, but there always will be. So I take what I personally believe to be sensible precautions. I avoid being drunk in public places, and I keep a rape alarm in my pocket when I'm out alone. If that means that the stranger rapist, like the burglar, tries someone else, then I've protected myself. If that's selfish, then sorry. The other person will of course be totally innocent and should not be blamed in any way.
These precautions won't of course help with the other potential rapes - office acquaintances, ex partners etc. But I will always try to protect myself in whatever situation I find myself, and being drunk out in public is one I really can do something about.
