Hiya, hope it's OK to add my thoughts here? (woman). My dh is very gentle, pro women's rights etc and we talk about this a lot, but I distinctly remember a conversation with him years ago where I explained that I don't go out at night alone, or if I do I'm nervous and take precautions (carry my keys, not distracted by music, watching my surroundings etc) and he was really surprised. He's got a number of sisters and they do the same and we'd been married a few years already and he hadn't noticed/it hadn't occurred to him that going out in the dark was very different for me than for him.
I think it helped him understand more about how women and men experience the world differently, how in the same situation what he'd laugh off, I'd feel scared.
From conversations with a couple of other guys I'd also call "good guys" a number of them were also surprised by this. when we talked about this more, it helped to also clarify why male behaviours that they see as minor (cat calling etc) are so much more threatening. Because they hadn't had to ever think about it, the impact of the physical differences between men and women on the way women experience the world had never occurred to them. Once they got it, a lot of what they saw as women complaining about minor things suddenly made a lot more sense.
I think everyone knows that women are (generally) smaller and weaker, but it doesn't follow that all men actually then realise how differently it affects how women move through the world compared to men.
I do live in an insular community so I'm aware my experience is probably not reflective of the general population, apologies if this just seems hopelessly naive - but I was thinking that rather than approaching men and boys and telling them all the things that men do that make women feel uncomfortable, possibly putting men on the defensive, and maybe triggering a NAMALT type response, maybe more discussion in schools would be helpful. So getting teens to see and experience the difference themselves, get them engaged in problen solving how boys and girls can work together to create a safer society.
For example, the blind museum in Israel gives sighted people the chance to get a small bit of an insight into what moving through the world without sight is like, giving them more awareness of a few of the obstacles blind people face. So doing something along those lines and triggering discussions in teens, showing how the differences between sexes affects how they experience the world, getting the kids on board with being part of the solution rather than kind of listing behaviours that are bad and telling them not to do them.
Getting kids involved in being part of the change.
(I mean doing this alongside moving towards making porn illegal, and other tools for change).
