After listening to Woman's Hour and other coverage as well as remembering the BBC documentary, I could see a link to Dr Stock's article about some men being dangerous and why there is need for safe spaces.
A whole generation or more were brought up in the shadow of the idea that women shouldn't go out alone by women who no doubt saw themselves through the experiences of ordinary women who were attacked for being out after dark.
We have internalised that lesson that because there are some dangerous men, we need protections of single sex spaces. It must surely play a part in why there is a generational divide. I wonder how younger all-inclusive women would understand and whether they would listen to women who were in Leeds at the time such as Joan Smith or some of the victims who survived or be bothered to listen to women who were brought up by mothers who had seen and understood more of the news reports than their children - like me. I do remember the coverage and trial but was a child/ early teen. I took part in Reclaim the Night marches as a student but was slightly too young to understand where the movement came from. And, yes, I clutched by NUS-rape alarm in one hand and my keys in the other.
It doesn't matter whether Sutcliffe was an anomaly or not, his actions scarred and scared a generation or more.
