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.)
