Thank you for gently correcting Maggie, Joe! Whilst it's true that "The Holocaust" unqualified has overwhelmingly been used since the 1970s only for the Nazi genocide of Jews, the word had been widely been used for that purpose since WW2, though perhaps not so exclusively. The wiki article mentions its use in the NYT in 1943 for the said genocide, for example. I'm not happy to see terms with slight pejorative undertones such as "appropriated" or "co-opted" to describe what is simply the evolution of language. In fact, in the Hebrew language the word "shoah" is the preferred term. Whether we approve or not, if we refer to "holocaust/the holocaust/The Holocaust" in almost any context today, it unavoidably invokes in the mind the Nazi genocide of the Jews. It's another example of how language works and the process is very democratic. We can all try to cling on to our sacred old meanings of words but it's generally a losing battle. In this case, I also think the loose use of "holocaust" in other contexts risks being disrespectful, as I say, devaluing the memory of the horrors of the Nazi genocide.

All just my opinion only.
