I think what needs to be remembered is that these aren't words on a page only - we are talking about people's physical safety.

Yes, okay, I will accept that some women 'like being beaten', as you say, but please let's put this in context. A woman being 'beaten' in a sexual sense is giving her consent and she remains in control. She can say 'stop' at any time. And in most cases the purpose of the act is not for the man to inflict harm, but for both parties to derive some enjoyment from the situation.

In the case of domestic violence, neither of these two factors are at play. The woman is being beaten against her will, and the man is seeking only to cause harm.

Perhaps we could start talking about honour killings too, since it's not too far off topic.
