It obviously isn't unwanted by some women, but others don't like it. I didn't and I know my daughter doesn't. Young men need to be told that 'no' means 'no' and that includes wolf whistling.
The man who wolf whistled the girl in the article said, 'I'm sure if she walks past again and she is lucky she will get wolf-whistled again.' He hasn't learnt anything, even though he now knows his wolf whistles were unwanted.
If she's lucky? I don't think so! The arrogance of him to think that she would be flattered by an idiot like him. Hopefully she has more self-respect.
Some of the comments on that DM article are quite enlightening. Hardly any of them criticise the male, but there are plenty who make further misogynistic comments about her. The comments on Twitter were worse, calling her a 'slut', 'an ugly bitch' and 'lucky if she ever gets one up her' and the like.
I agree with you, thatbags, about attacks, but they would be dealt with as assault/ABH/GBH. It would appear that calling a female a slag or a slapper isn't a crime, whereas calling somebody a name related to religion, race, disability or sexual orientation is. That seems to be the issue and it's getting worse.
