It's a silly thought experiment.this isn't even a logical grouping lol the populations share no commonalities, I mean just look at whats happening right now in Israel and how their treating their Semitic habesha brethren lol
But the Beta Israel spoke a Cushitic language a few hundred years ago. They are not ethnically Semitic.
The same is true for most Habeshas. They used to speak Agaw Cushitic languages in the past.
