"But it is also sensible to have terms which separate them out."

That's great, if you are for some reason discussing something that is irrelevant to the mood of my comments.

But I'm not, and I still hold firm: it is really irrelevant to split hairs (and only gives straws for the 'nasties' to clutch at) when one is discussing considering the life of any human "cheap and of a lesser value than one's own", whether they die with any particular narrowly defined group of humans or separately, in mass butchery or in lesser numbers, by the action of any other narrowly defined (and not necessarily mutually exclusive) group of humans.

Murder is Murder, by any other word, still the same thing.
