It is indeed very sad.
Very sadly too, I suspect that there are few adult women who have never experienced some level of sexual harassment. Nothing significant mostly (I hope) - just that sort of low level, pat on the bum as you walk by, your appearance being the first thing people comment on, being unable to walk into a bar or a restaurant alone without some bloke coming over and trying to impress with some aspect of their lives. Sometimes these men can become incredibly hostile if the woman they are harassing doesn't seem thrilled at their attention. Not for years now but I have in the past had men screaming at me that I'm fat, ugly and they'd never have sex with me anyway. Always was interesting to hear from a man who has spent the previous half hour trying to get me to go home with them.
We see it all over here in the UK. Walk into pretty much any bar you come across and there are likely to be a bunch of men standing alone - usually at the bar - enjoying a drink as they go about their day. There also tend to be mixed groups, pairs or groups of just women and mixed pairs. Almost never will you come across a woman on her own who isn't waiting to be joined by somebody.
I like going to bars and restaurants on my own which is why I've noticed so often that I am the only woman alone doing so.
To me, one of the real benefits of the assumption of monogamy is that to ward off unwanted attention, often all I need to do is stand next to a male friend. Or sometimes say that yes - I have a boyfriend. It gives a harasser an out without them feeling rejected which means that they are less likely to behave aggressively.
It is completely understandable for pretty much any woman to say that it would be nice to have a male friend who isn't interested in sex and won't pester them.
