I've been thinking about this further as I've been cooking tea.
I think a lot of women have the knee jerk NAMALT reaction because they are, or someday may be, mothers of sons. You see it on threads like these "not my lovely boys" etc. I'm not sure you'd see the same exception made for daughters on male dominated sites, but there we go.
The thing is, the men who treat women like shit are ALL someone's lovely son. These cases of men on sports teams being accused of raping girls and women are a good example. Half a dozen or more men-often boys in their late teens, actually - who either stand by or participate as a vulnerable girl is raped and assaulted.
Not all of those boys are evil monsters. Many of them have been raised "well", in "decent homes". Many of them will have mothers who work, fathers who do housework. Yet they still see a drunk girl as "asking for it" etc.
We need to look at what men are capable of with clear eyes. Even the ones we love. When have you ever heard of the girls hockey team gang raping a drunken man?
I am pregnant with what I think is a son. I have an older daughter. I will do my level best to raise a son well, and not make differences between a boy and a girl, but the real test will not be whether he makes his bed or sees his mum fix the car and his dad weild the hoover - it will be what he does when he is a young man, dealing with the pack mentality of other young men. Or when his wife has a baby. Or when he finds himself part of a sexist conversation at work. Plenty of "nice guys" stand back and keep their mouths shut in these situations, even if they don't actively participate
It's so insidious too. I work in a school, and you always hear comments about boys being more boisterous, or poorly behaved. From my experience, it's not that they can't behave, it's that nobody has expected them to, at least not in the way girls are. Many adults are harder on girls, and will tell them off very quickly, whilst the same behaviour in a boy will sometimes not even evince a comment. When a girl has her behaviour corrected, there seems to be more emotional guilt tripping involved "that isn't nice behaviour, how would you feel" whereas for a boy, it is more punitive "stop that or else". Again, this is just from my own observation.
Men are also encouraged to think of themselves first. When I was 12, I started my periods. I also more or less thought I was Frodo Baggins. I was obsessed with LOTR. During one typically long and painful period, I realised that if I was attacked by orcs at certain times of the month, I'd be fucked, at least unless I'd taken some paracetamol and just changed my pad. Middle earth would have been lost, thanks to my menstrual cycle 
joking apart though, boys can "get up and go" in a way girls often feel they can't - at least not without checking the calendar, stocking up on emergency tampons, and keeping an eye out for people who want to rape them. Of course having a normal period shouldn't stop a girl doing anything, but it does when it's seen as something shameful and hidden.
I'm rambling a bit now, but this has made me think
