Who are Semites?
Semites are a diverse group of people with Arab, African, and Asian backgrounds. It is a cultural misappropriation to use the term to refer only to Jews.
According to dictionary.com, they are:
a subfamily of Afroasiatic languages that includes Akkadian, Arabic, Aramaic, Ethiopic,Hebrew, and Phoenician.
Based on https://www.merriam-webster.com, they are:
a member of any of a number of peoples of ancient southwestern Asia including the Akkadians, Phoenicians, Hebrews, and Arabs
b: a descendant of these peoples
Wikipedia’s definition is in keeping with the above though their presentation is confusing.
All the definitions agree on the fact that Arabs including Palestinians are Semites.
The cultural misappropriation of the term to only refer to Jews is yet another instance of cultural piracy.
