The reasons why women who are harassed don't complain are also generally similar. They are afraid that they will not be taken seriously in a male-dominated society. The fight usually gets ugly if it gets to a court, with lawyers raking up unrelated issues. In a country like ours, unfortunately, the woman if single, may not be able to find a husband-again, the same patriarchal problems.
Hopefully, the opening up of near and dear ones will at least give courage to more women to oppose unwanted attention (or worse), and stop many attempts in their tracks (and men to support them when they speak up). In a Utopian world, molestation should not happen. But then, we don't live in one.
