Well, you probably only hear about the women who have been attacked.
I was talking about strangers however (in the context of being scared when alone in public places) but if I'm not mistaken the overwhelmingly majority of rapes/assaults come from somebody known to the victim.
It would make more sense to be scared of your partners and male friends/colleagues horrible as this sounds.
I'm not talking about being attacked thanks.
I'm 'only' talking about the (countless) low level stuff - and without exception - every single one of the low level incidences I've experienced has been from a stranger.
Grabbed at in the street, groped in bars, pubs, clubs, public transport. Whistled at, shouted at, commented on, etc, etc, etc, ad nauseum.
All the stuff that (especially) young women have to put up with as routine from men (it happened almost daily for a significant period of my life) - all the low level stuff - that's from strangers, because men you actually know don't tend to do that sort of harassment.
Men you know will lift it up a bit to next level, and I've been fortunate enough not to experience that.
It's because of all the low level stuff from strangers that I still have that left-over, visceral reaction around some men, in certain situations, even though I'm now middle-aged.
Men have no idea what it's like to experience this sort of low level (but with a very real fear that it could escalate) constant harassment from other men.
