there is no question what it means, you simply personally disagree with it
and since you definitely aren't an authoritative body on the definition of words, your personal pedantic insistence that the word mean only what the strict etymological roots imply, rather than how people actually use it, is irrelevant

it's quite telling that you seem to view usage of the term "cultural genocide" to refer to cultural genocide as a bigger issue than actual cultural genocide
don't like people using the correct term to refer to the action? maybe get those perpetrating the action to stop, instead of telling everyone we're using the wrong words to describe it.
