I have no idea why some in this thread are talking about men 'looking' at women... this is about harassment, not just looking. And if being shouted at in the street makes a lot of women uncomfortable (which it does, me included), then it's unacceptable.
Whether you think women are being oversensitive or shouldn't be offended by it or whatever, is entirely irrelevant because the fact is, we are made uncomfortable by it.
What I don't understand is- what's the point? Do you think shouting 'nice arse, love' at a random stranger has ever got her into bed?
