The 19th century German coinage "antisemitism" was never a neutral label for "opposition to Judaism", it was a racial science slogan that recast Christian anti-Judaism as a biological war against "Semitic" Orientals

At the time it had no connection with Zionism

Because the word now circulates without that historical packaging, many people take "Jew" to be a racial category and imagine Jews, not Arabs, Assyrians, or other Semitic language communities, to be the only Semitic group, an assumption that reproduces the very Nazi racial taxonomy the term originally served

Its very design, framing Jews alone as the quintessentially "Semitic" target, censors every attempt to talk about the Middle East, because it buries the shared Semitic matrix (Arab, Assyrian, Hebrew, Aramaic, etc.) under a racialized badge that only sticks to one side

Once the vocabulary itself encodes a single victim story, any mention of parallel or overlapping suffering sounds like denial instead of description, and the conversation stalls before facts can even be named

The Nazis had no problem allying with the Arabs including the Palestinians in WW2, so there is evidence these weren't placed in the same racial category as Jews.

As these racial categories are all pseudo-science anyway, their only meaning is the meaning attributed to them by the racists. So you can only complain to 19th century Europeans for not being as racist towards Arabs
