As for "tell men not to attack women" that is right up there with "tell drug addicts not to break into cars" or "tell people with money problems not to embezzle" as ways to bring down crime. There is little one can say to anyone who thinks this is a reasonable suggestion.
I get your point re saying it now.
For me though, the point is that we need start saying this to the little boys of today. We think were doing that, but we aren't.
Society still teaches children that boys are able, girls are not.
Girls need to be worthy- pretty, kind, amenable. Girls are wallpaper, they are there to cheer up the view.
What girls choose to wear makes a statement; what they choose to wear can have an impact on what happens to them. The choices they make, will impact on what they might be subjected to.
The problem is, when we give little girls those^^ messages, we give it to little boys too.
I think there are some ways where our society does not give out good messages with regards to sex.
But overall we do give out some pretty significant messages about sexual assault being bad, and particularly the kind of sexual assault where a stranger attacks you in the street - there is not much ambiguity about that, it would be difficult for anyone to tell themselves that our society is ok with that. If they do it anyway they don't care, perhaps they are psychopaths which seems to be a fixed proportion of the population no matter what we do - or they don't self-regulate, which is a complicated problem on a society wide level. But it's not that they think society is ok with it which is why they don't do it in the middle of a crowded street.
I have wondered more than once what people think the "natural" level of this sort of crime, or sexual crime more generally, would be in a society that really didn't care about it. I think it would be a lot higher and more blatant that what we see. I think our social norms already make a significant difference to the amount of this kind of crime that happens.
I think there are some things that might lower it. There are some crime prevention things that might be the most direct approach, especially for stranger assaults - things like stopping crimes like this before they escalate, which means tracking incidents and so on.
Socially I think the things that might make a difference are not so much about teaching people "ideas" like respect which we already do. (Though arguably we live in a society that values people as commodities generally so of course that will spill into how people value sex. But that isn't a small problem to tackle.) But things that are not what we teach - do we think sex (the activity) is a big deal, or something pretty unimportant that is a nice casual recreation? If we think it's the latter, will that affect how people think about unwanted sexual contact? Probably, because these ideas are connected. But then, do we want people to see recreational sex as questionable?
Similarly, many behavioural changes could bring down sexual assault. The curfew one above, maybe, but actually the biggest, involved in a huge number of assaults including ones where the perpetrator is known to the victim, and domestic violence as well, includes alcohol. There is a huge weight of evidence that a less accepting attitude to over-drinking would result is a real lessening of many types of crime. It would be very good for women in that respect.
On the other hand, do we really want to tell people, or have less social acceptance, of drinking/partying? Some people think the freedom to do those things was what feminism was about, or partly about.
My point being here - there is no point where it is likely we will eradicate sexual crime, any more than the other basic crimes. Certain social conditions can make a difference, but many people consider them restrictive. Discussions about how to do it tend to be very speculative - things like tell men not to assault - and not really very willing to dig into concrete possibilities, which is kind of useless.
