Nah. The term Semitic was coined to refer to a class of languages, not people. The term anti-Semite was used by anti-Semites such as Heinrich von Treitschke and the
Antisemetic League to describe their anti-Jew stance. This is the word as it means today.
The modern attempt to make it refer to Arabs and other Semitic-language speakers is itself an anti-Semitic attempt to rob the term of meaning. Nice try, though.
