The Orthodox already do.
2) The killing of Jews by the Nazis -- You do not like the term The Holocaust for this tragedy?
The Orthodox really don't.
3) The abortion of babies as a widespread industry -- You do not like this to be called a holocaust?
I doubt the Jewish people do. I respect their wishes on this one.
My only (mild) confusion now is the term for the abortion disaster. As you have pointed out, "holocaust" is a Greek word. And if people refrained from using "The Holocaust" as an alternate term for Shoah, then I guess I don't see why Jewish people would take much interest in how anyone else uses a particular Greek word.
I feel that "a holocaust" is a long-standing term to describe widespread, horrific killing. I believe that it is in common usage in just that way.
On what grounds would Jewish people oppose describing abortion as a holocaust? I could perhaps see why if the Jews wanted Holocaust to be a specific term for what the Nazis did, but you are telling me that Holocaust is not an appropriate term for what the Nazis did. On that basis, I would think that "holocaust" becomes an available term to describe what America is doing today.
