If sex were to be added to the list of characteristics protected against hate crimes, then these killings would be hate crimes against women, and we could call them that.
That should have happened long ago.
Also worth noting that even if the media stops calling it an honour killing and calls it a premeditated domestic murder or something, doesn't mean that the criminal justice system, psychologists, criminologists, etc, will forget that this particular concept of 'honour' is at the root.
Yes, and those are the groups of people who need to understand the murderers.
The general public, though, just has to strongly disapprove of murder, and I think it is a good thing if such a murderer sees on the media that people do not think he was in any way honourable, that they don't even mention that he thought he was, that they treat him like what he is, a common murderer who murdered to further his own selfish goals.
I mean, is it necessary for people in general to be able to identify it as a phenomenon? If the general public knows that it is a thing, then other would-be murderers also know that it is a thing, and might imitate it.
If we used another highly specific term for the same thing, then statistics on how common it is, etc, would still be possible, and that's what matters, isn't it?
