It's used as a synonym for "victim".
In many contexts, yes, which I would stand against because in both cases it's used to enable and exacerbate the victimhood culture.
It may be the case that it might be helpful for some victims on an individual basis for psychological reasons
That's how the, shall we say, 'alternate term' came about - "Victims are dead, survivors make it through", sort of idea.
It was intended as the antithesis, both to the, again shall we say, 'misappropriation' of the word victim, and the negativity associated with being an actual victim. A good number of 'victims' outright refused to let themselves be classified as a victim, much less defined by it.
As with all such things, someone inevitably nicks it for their own (political) ends, but if it genuinely helps genuine people with genuine issues, then it still deserves recognition in that context, too. I'd just hope most people could tell the difference.
it was never going to stop anyone using victim power for political purposes
Not at this point, perhaps, but at least people tried...
They're not dead until they are. I'm very wary of the idea that rape victims are better off dead than alive, let alone the idea that they are already dead while they are alive.
Dead in the metaphorical sense. It's obviously something you cannot prosecute unless they are
physically dead.
But even in the metaphorical sense, for some victims it
is a very real thing rather than anyone's idea (and I'd suspect if anyone did come up with that idea, they weren't one of the victims or even those carers involved afterward, either)... and it's still damaging enough that suicide is far too common an end result.
