Granted, maybe your point is that we shouldn’t consider all these details when determining whether or not a massacre is part of a genocide campaign,

No, no, you outlined my position and our conflict just fine here. ‘These details’ are irrelevant. That’s my point.

but it’s generally a bad idea to ignore context.

There is no context that can justify it. It’s like saying one has to look at the context of a rape before judging it. You really fucking don’t.
