I don’t know why you would assert this like it’s any of those things. You can look it up if you don’t believe me; you would be considered extremely weird for talking about “Semites” as a coherent racial or ethnic category around anthropologists.
(By comparison: nobody who isn’t a racist talks about Japhetites or Hamites, but these are the coextensive groups implied by the existence of Semites.)
I have simply referred to speakers of Semitic languages. You are the one concerned about whether this group comprises some kind of orthodox taxonomic grouping.
Speakers of Semitic languages are not "Semites" either.
I'm sorry for responding as though we were using the received definition, because we're now solidly in the "Elon Musk is African American" quadrant of stupid I/P meta-arguments.
