not exactly by your logic then all Altaic ethnic groups are considered Mongol those tribes as related to each other as a Kurd with a Lor with a Bakhtiary ,they are as related as a Sistani with a Baluch
No, you are mixing up ethnicity with clan-tribes.
If we go by your logic and that of map, Kurds should be divided into hundred pieces, like Gorani, Sorani etc...
I mean no one can say that Shahsevens are some kind of ethnicity. They are a branch of Azeri Turks, like all other tribes there.
Qashqais are closely related to Azeri Turks but they are not Azeri Turks, however you can't claim such a thing for these tribes who speak Azeri Turkish.
