I think the point being made on a lot of these threads (certainly the ones I've seen) is that, precautions are just that, precautions, but if a man decides he's going to rape or attack you, it won't matter that you're sober, covered from head to foot or any of the other advice women are given to protect us.
Well, of course, if a rapist has fixated on you as a victim, the only thing you can do is to incapacitate or kill him. There should be more advice on how to do that.
Most of the safety advice is, sadly, a kind of "make sure he rapes someone else" advice. Making it harder for rapists to get you mean they will rape someone else, not that they will not rape at all.
