I think what this thread has thrown up there is clearly a divide on how well all view this. Some have enjoyed that form of attention that's their prerogative we are all different. I'm going to stick my head above the parapet and say that maybe you have to be a woman to appreciate just how unwelcome such situations can be imagine be, although my husband definitely got that when the subject came up, particularly as a father and grandfather of girls, he certainly saw the crassness of men who were prone to wolf whistle and cat call at random women, although we both agree with young men it's all about bravado. We also agree that prosecuting such men is a step too far for what is essentially in most cases banal laddish laddish behaviour.
However, I would reiterate, like others, all that stared quite early for me, 12 maybe, yes it was the time of of the mini skirt and I remember walking home from a friends and becoming aware of being whistled and shouted at and then the car slowing right down and crawling along the pavement behind me for a short while before it sped up again, that feeling of alarm stayed with me, I didn't want that attention and at that age it was unnerving. Later on as a young woman, I felt annoyed at being objectified, exasperated when I was walking along alone with my thoughts minding my own business and never flattered, unwelcome inanities from strangers, why would I have been! not the same as office banter which I often did enjoy with male colleagues who I got on with.
I have heard that it happens in reverse and young men in the workplace have been on the receiving end of female sexist comments. Also unacceptable imo.
