They don't exclude men. The ability to get LEO to give a crap varied by jurisdiction but plenty of guys have managed to get consequences enforced on their male or female harassers.
Mostly I think it's a result of the average LEO/judge being older and having no clue what the consequences are of the ongoing harassment. It's definitely true that lots of judges/prosecutors have told people to "just get off the internet".
Laws don't exclude, but their application and interpretation sometimes does.
Not long ago in my country, there was a proposal to add funding to research domestic violence committed by women.
The women's organisations of all major political parties (except one) signed a common statement which opposed the funding of this research. They said it was diverting attention away from the main problem which is violence by men. This they were saying without looking at the actual numbers. They were in fact opposing research to find out and evaluate the actual numbers.
The actual numbers in this country from crime statistics: in 2008, the victims of domestic violence in homicide and grievous bodily harm cases were 116 men and 111 women. This was irrelevant, according to these political women's organisations.
The issue was raised to public consciousness when a man, assaulted by his wife, brought to publicity the response he had got from calling 112 (emergency number), where the police dispatcher said to him: "What, are you letting a woman beat you up?"
Yes, laws are in principle gender neutral, but their application is in many cases favouring one gender. Often the favoured gender is women.
There is a huge gender bias in play. In the US(and probably most other western countries), domestic violence is viewed as only something that men do to women.
It's treated as a joke when a woman is violent against a man and it's completely ignored that lesbian couples have the same rate of domestic violence as heterosexual couples.
Mostly I think it's a result of the average LEO/judge being older and having no clue what the consequences are of the ongoing harassment. It's definitely true that lots of judges/prosecutors have told people to "just get off the internet".
