I think that instead of saying "believe women", it is better to say "don't disbelieve women". The difference may seem subtle but if you understand the difference, you will know how important it is. Obviously what a woman wears etc is no defense in a case of rape or sexual assault and only one expression of reluctance from a woman should be enough to tell a man to stop. Obviously the words "woman" and "man" in what I am saying can be swapped and it will be equally true. When you say, "The problem NOW is that many cases don't start from "the middle", or a neutral clean slate.", I totally agree with you and that is the problem that I have tried to point out.
