"Vulnerable people of the opposite sex". Do you mean girls or women who readily approach strange men Rov?
I go for a six mile walk every night at times ranging between 1am and 6am. I am astonished at the number of young girls (many of whom can't be more than 14 or 15) and women walking alone who approach me at that time of the morning. The last one was a girl of about 14 years old dressed in a miniskirt and high heels who crossed the road to say "'ave yer got a cigarette mate". It was 4.45am, the road was silent and there was no one else around! I just said I didn't smoke and kept walking. There are many other similar examples - quite a few say "'allo mate, can yer borrow me some money!" Quite a few of those girls have been drinking and many get abusive if I don't produce cigarettes or money which really upsets me when they insult me like that for no reason.
I'm not the type to attack women or take advantage of them but I quite understand how it happens. Of course, men can be blamed for attacking women and women have the right to walk the streets in safety - but there has to be common sense too. This generation of girls have to learn not to stagger round the streets in the early hours, not to approach strangers in the way they do and not give a strange man a stream of four-letter words if they aren't happy. Not only are individual men and women to blame for that, but it's society's failing too.
