I'm just thinking about this.
My parents were very strict, they drummed safety into me a lot, I think now in my 30s I'm an extremely cautious person because of that. We were always watching things like crime watch and having discussions about things.
However in my teens and early 20s I still did absolutely loads of stupid stuff that my parents don't even know about. I put myself in loads of dangerous situations. My gosh I can remember getting into cars for lifts on a couple of occasions with strangers.
When I think back though, nothing ever happened to me in those circumstances. The time something did (I was threatened), was actually with two men that my friend had known for a long time.
The time I was raped was in a relationship, the times I've been groped and harassed have been at work, on public transport, going up the high street on my lunch break, on the coach on a college trip, hell even at school ffs. All in the daytime and stone cold sober.
I know that's only my experience and not evidence, but it tells me women aren't safe even in normal day to day life.
I believe there's a problem with excessive drinking in this country but I don't think it has much to do with rape (overall), and I think to suggest to women otherwise would be doing them a disservice.
