This is our problem with using gender-neutral language to talk about a very sex-specific problem, which is men's violence against women.
I think that having broader language is probably important, because what we actually want the judge to focus on is this male violence against women. Is this the kind of dangerous situation where other people are going to be targeted and brought into it, like parents or the new boyfriend, or is this guy fixated on her? Is he actually presenting danger of male violence against women? I don't want narrower language unless it's sex-specific to identify.... This is the core of the problem that we're talking about and that we're trying to target with this legislation.
I'm not sure that's a really great answer. I'm asking for a broader definition, which is the opposite of what you were referring to in terms of narrowing the meaning of “dating partner”. I would broaden that to say “men who want to date, who are rejected, who then won't leave the woman alone, and who fixate on them”.
