I think there needs to be a seperaration of two points here. First off I think people are always going to meet in passing, and I don't think every time a guy strikes up a conversation with a woman he doesn't know he is being entitled, and also believe it or not women are perfectly capable of approaching men and striking up a conversation, such has happened to me many times.
That said this video highlights a major problem, the woman in question was not telegraphing in any way shape or form a desire to socialise or communicate. Reading her body language she had the look of a person who was simply trying to get from A to B through the medium of walking! Her being beautiful was beside the point, and it looked to me like she was just wearing comfortable clothes.
Another point that I think is indefensible are that the comments were exclusively directed at her appearance. I am struggling to think of many occasions where women have approached me and blurted out anything overtly sexual or objectifying like that, and she had what 100 instances in 10 hours? That's like one every six minutes, and I think that would be enough to piss me off immensely. Especially if I was just happy in my own headspace trying to get somewhere.
