@claralistensprechen3rd An Austrian Jew-hater coined the phrase in the 19th century to refer specifically to hatred of Jews and recast it in what was then shiny new pseudo-science about race.
It's never referred to any of the other peoples who speak Semitic languages.
As for indigeneity, Jews are those whose ancestors didn't assimilate to Arab culture & religion when the caliphate moved up from the Arabian peninsula.
You're making so much shite up.
