What do you do if you are not someone who has been harassed, or have not seen anyone be harassed? That is more a question to me than to you. I guess there might be something right there.
Most of these incidents that I have read have been harassment where the victim's response is muted and does not draw attention to the harassment when it happens. Perhaps, in a society where people take their perceived self-respect a little seriously, they continue to engage in this behavior not because they won't get referred to the police, but they won't even evoke a whisper. At least in all cases where the victim knows what is happening to them, and can raise the issue. I think that might have made the issue claimed to be present everywhere to be there on every mind too. Won't you think that would help?
