If you can define that threshold, you don't need terms like "social murder" anymore.

Nobody can really because it's complicated. Or, at least, nobody can agree, which is why we have the terms. However, I think the terms have some validity, because the broader concept does.

I mean, is Hitler a murderer? Is your run of the mill burglary gone wrong worse than the Holocaust? Obviously not. So there has to be some kind of understanding of organized death.
