That didn’t start till the late 1970s and was because of a Meryl Streep movie…

Yet for decades after the war, the genocide lacked any formal title in English except, perhaps, “The Final Solution,” the term the Nazis used. In Hebrew, the calamity quickly became known as “Shoah,” which means “the catastrophe.” But it wasn’t until the 1960s that scholars and writers began using the term “Holocaust,” and it took the 1978 TV film Holocaust, starring Meryl Streep, to push it into widespread use.

And yes, like I said…

for decades Israel has led a movement to ignore every other group that was targeted by the Nazis so they can claim they’re the only victims of it

So what does it matter what the publicly edited Wikipedia defines it as?

1978 isnt ancient Pompeii, we have records of what it was like, lots of people lived thru it and are still alive.

Why pretend?
