They stole it from "Persia", Not - Lol.
Cronos often uses the word "Irani" interchangeably with "Iranian" or "Iranian People". No criticism of Cronos, but it can be misleading & confusing for those who are unaware or who want to stir up.
Kurds ARE a group of "Irani" people.
Iranian (aka Irani, Iranic, Aryan) is a broad umbrella term for all those ethnic groups, who belong to, and share the same Iranian (aka Aryan) roots, racially, culturally and linguistically. For example, Persian, Kurd, Balouchi, Lor, Bakhtiari, Azari, Gilaki, Mazandarani, etc..
I should probably say Iranic :)
