No - that's simply not true. You do not get to define language to suit your needs (nor do I, obviously). Language is a living thing, and words mean what people decide they mean. As such, I'm positive you're aware that opposite sides of a conflict will call what the other side is doing murder.
Actual use of the word defines it's meaning - not a textbook definition.
Also, I utterly refuse to debate semantics. You know precisely that I mean.
So the definition of the word is off the table. If you have an actual point, let's hear it.
Otherwise, I say we leave well enough alone, and move on.
