Apparently "builders live in fear of being accused of sexual harassment if they wolf whistle"? How awful for them - but hadn't it crossed their minds that there's a way of avoiding all this anxiety - stop wolf whistling!
Iam64's recollections regarding the routine encounters that her daughters experienced - ".... the amount of horn pipping, chaps hanging out of windows making the universal sign for masturbation. The girls reassured him [their dad] that they had got used to it, and to ignore it" - surely suggests that a lot of this sort of male behaviour has very little to do with complimenting a woman and a lot to do with the inflated sense of their own importance that some men have - a presumption that a woman should care what their opinion is of her.
I, and I'm sure some other women, have always disliked this type of male behaviour - long before the, in my opinion, rather silly phrase "political correctness" was ever thought of. This is about more women now saying that they are unwilling to continue to collude in their own sexual objectification.
I would also say that this is not a men v. women issue. Increasing numbers of men, particularly in the US, have supported a campaign against this sort of street harassment.
