If you see a straightforward dividing line between harmful and not-harmful I'm not surprised you don't take this very seriously, goodbye.
It's a very artificial line, in my opinion: the reality's more of a continuum. And who gets to draw the line, anyway?
If a man asked me to go in his car when I was a teenager, but didn't try to force me when I said no, is that harmful or not? I wasn't harmed, but presumably might have been. Maybe another girl was.
My friend and I got flashed at on a train as teenagers. We laughed at him. We weren't harmed. So was it harmless? It's apparently a gateway crime for some sexual offenders. The man recently convicted of assaulting and murdering a student in Hull had committed a string of offences like that. Sometimes he just peered through people's windows to watch women, and admitted to cases where the woman wasn't even aware of it at the time: how do you measure the harm then?
Or what about when a man who makes off-colour jokes to or about women is put in a position of power, maybe as a judge or even the head of a college/university: is he likely to take cases of assault and harassment seriously?
How do you measure harm? If women MPs receive online abuse and rape threats, as they seem to more than ever, is that just harmful to the women concerned, or to our whole political system if fewer women are prepared to put themselves in the firing line?
And what about the greater prevalence of online porn? Is that harmful or not? Use of violent porn in particular is regularly cited as a factor in abuse and murder cases, but does it demean women generally?
If your clients/colleagues in the City didn't upset you, goodbye, but contributed to an ethos where women weren't treated with as much professional respect as men, how harmful is that?
Oh, for a world of simple dividing lines
