Magicjamas - nice to see you in this section. 
I remember we exchanged posts on another similar thread.
Not sure if you saw my post on the other thread about why I thought the OP was not being unreasonable?
Anyway I wanted to address your comment "this is one area I really struggle with, as it seems to remove any level of personal responsibility at all as long as you are female".
I struggle with it a bit too, even though I deem the "be careful" comment to be sexist (in this context).
I think that all responsible parents teach DC about road safety/"street" safety/personal safety/alcohol safety/safe sex/self defence etc.
However, I don't want "be careful" messages to lead to women feeling that they have "put themselves in danger". The less women walking around etc the less safe the street are and the more likely that society blames a victim.
It's just that I can't accept that it is "wrong" for women to walk around on their own after dark. It's just so limiting
. I think it is so ingrained for many women that it becomes normal.
eg When I left university and lived in London on my own, my Mum had me really really wound up about me being safe getting home. I used to have a rape alarm in my pocket, keys ready and very very alert as I went down the side street to my flat.
The myth of a stranger attack being my most likely risk (which my Mum lived in fear of for me) was strongly ingrained in me. It is only recently that I realise that my Mum would have been very pleased if "nice young gentlemen" from work were escorting me home - now of course my risk of rape would have been much higher from one of these collegues.
Sorry bit rambly - anyone care to elaborate re personal resonsibility/safety v the fact that men can stop them selves from attacking/raping?
How does theory translate into practice for you?
Recently I was at a function (without DH) and my ex-boss started walking me back to my car and I didn't even realise it. We were walking along and I said "oh you're in this car park are you?" and he said "no I am walking you back!". I wasn't offended at all! I see this as different to 2 policemen on bikes cycling past saying "be careful". When he walked off though I thought to my self he is probably at risk of being mugged now as a lone bloke!
Also re "if the "non consenting" (by reason of incapacity) girl could be equally culpable of assault, if she performed various acts on a boy, who was also, by reason of incapacity, incapable of giving consent." - you said that no one ever answered you re that Q.
Yes women can be charged and convicted of sexually assaulting men. However as rape and sexual assault is overwhelmingly men doing it to women it is seen as a "gendered crime", that is not to minimise women on men attacks but to recognise that gender has some bearing on it and deserves focus and eg cultural shifts/public education etc. Hence, for example the Home Office's Call to end violence against women and girls: action plan.
