This is a cop out. No one is asking men to try to spot and prevent that man over there from attacking a bunch of women tomorrow. But as a society, we let these men build up to this too often because we don't challenge them when it starts small. Do we really think the man who killed the Hunt women had never done anything questionable before? There's an element of the "broken window" doctrine to this. If we can stamp on all the little things, then the medium things, then the bigger things are less likely to happen. Its not likely they'll stop completely, but they'll be less.
Let me ask you this: do you think it's just in a man's nature to n urder women? And that's why WOMEN don't murder people at anywhere NEAR the rate men do?
No, it's because on some deep instinctive level we tell men that their rage and their shittiness is okay so that when it escalates, they don't have the internal switch to say "no".
I came close to being date raped once. the man involved was, at heart, a good guy. I was at uni - I was 19. I knew this man and he knew me. We had a few drinks and started some drunken snogging. I somehow let him talk me into going back to his place even though I had no intention of sleeping with him. He knew that, I think. But he kept pushing and pushing. But I kept saying no and eventually I realised this was getting out of hand. I got scared. I managed to stop things and managed to get home.
But for many years after, I knew that the ONLY reason I managed to do that was because I had been 100% clear from the start. If I'd been wishy washy. If I'd let him take off my shirt or my pants, I am 100% certain that he woudln't have stopped. He knows it too - he apologised to me.
I tell this story not because I think women should have to say no from the start in order to prevent being raped but because we need to say no to men from the start in many many other situations so that they learn to accept no, as SOON AS IT IS SAID.
