> that is no argument for fixing a particular meaning or context as more important or 'native' than any other
You missed from my argument that the above statement is part of my argument: it is normal for language to also represent controversial (contextually) cases, but «that is no argument for fixing [such] particular meaning or context as more important» or having priority over, especially, its core meaning.
You are missing that I oppose an appropriation, that reduces of that richness of applications to a "yes but, you see, we cannot forget what happened in Khartoum, there is no return from that episode and now if you mention it I can only think of the event". No, the richness is intact, you are covering it. And the subsequent argument I proposed, replying to you, contains: beware while covering it of not being supportive to some political effort you would otherwise oppose.
Example: one extremist a few years ago apparently instructed his followers, their music shall be that of Depeche Mode - their guts should resonate with that; the authors of «the grabbing hands grab all they can» and «we are going backwards, to a caveman mentality» showed being less than impressed. If people stopped listening to Depeche Mode because an extremist finds their sound instrumental to hook underdeveloped prefrontals, and now there is an association, they should be dehypnotized. The extremist or another could have invented that 'depeche' is now a world that means their attempt world domination: I am not saying that Gore Gahan and Fletcher have a full right to the word, I am saying that one would not be justified to call the word "now embarassing" because some fool came up with his low fumes.
If we measured our associations with the worse in society, we would be in deep trouble, repeat:
supporting and justifying associations following the worse in society is a recipe for collective damage.
Never empower the "wrong side". If already you allow them to bend your vocabulary...
Technically, for the rest: a term is a pattern, one can apply it metaphorically to a large number of cases. (Its transliteration is largely irrelevant - 'jñāna', 'gnoscere', 'know'...) The core meaning is found navigating to the "original" pattern behind all applications. Etymology helps you with that. Forgetting the core pattern is what I called uprooting.
