‘in recent years’
This isn’t something that people came up with recently. It’s been the established definition forever. What you’re doing is attempting to conflate the goals of Arabs with the goals of the nazi party.
Here’s some historical context to chew on:
"Nazi harassment of Arabs began as early as 1932, where members of the Egyptian Student Association in Graz, Austria reported to the Egyptian consulate in Vienna that some Nazis had assaulted some of its members, throwing beer steins and armchairs at them, injuring them, and that “oddly enough” the police had not arrested the perpetrators, but the Egyptians.[27] The Nazis attackers were later acquitted; one of its officers, penciled the word “Jude" [Jew] after the names of three of the attacked Egyptians. In February 1934, the Egyptian Embassy in Berlin complained to the Reich Ministry of the Interior that a student had been attacked and insulted in a dance hall in Tübingen. The perpetrator had complained that he was not permitted to dance with a “German” because he was “black” and of a “lower race” and had punched him. The attacker was not punished.
The Moroccan Mohamed Bouayad was killed in a gas chamber in Mauthausen in April 1945.
While Arabs were a small population in Europe at the time, they were not free from Nazi persecution.[28] Racist incidents against Egyptians were reported as early as the 1930s.[29][30] The Nazis also sterilized hundreds of “half-breeds”, Germans of mixed Arab/North African heritage.[31] On the onset of war, Egyptians living in Germany were interned in response to the internment of Germans in Egypt.[32] Tens of thousands of French colonial soldiers were imprisoned after fighting alongside French forces in the Battle of France.[33]"
As you can see from the above, Nazis treated Arabs as bad as they treated Jews during that time because they didn’t care about the difference between Arab and Jewish peoples.
So Israel is using the Nazi’s definition of Semite. Pretty sure the logic to stop using that would be the same as the reason we stopped giving credence to the Nazi’s definition of Aryan.
