Men are subject to more violence than women - but it is, in almost all cases, violence perpetrated by other men. So, with a few exceptions, men are the common denominator.
I'm fairly sure most women are wary when they are walking alone at night, but sometimes there is no alternative other than to stay at home or to order an expensive taxi - and even taking a taxi doesn't guarantee safety - look at John Warboys. Anyway, why is it that a woman's actions are so often the focus of so much coverage on issues such as this? It is the abberant behaviour of men which needs to be the focus.
I think women should stick together on this and not say "nothing will ever change, so it's up to women to restrict what they do". It is up to parents and schools to teach their children that boys and girls should treat each other kindly and courteously and that it is certainly not manly to speak to, or of, girls or women in a demeaning way or to use their greater strength to bully and violate them.
