You mean just like Yezidi Aryans and Indian/Pakistani and other South Asian Aryans are one race?
There are clearly many direct links between the ARYAN Ezdi Kurds and the Eastern Iranic people in South Central Asia.
We are not just linked by language.
It is mostly the Iran_ChL ancestry that links Aryan Ezdi Kurds with the Eastern Iranic people. Ancient Eastern Iranic people of South Central Asia (such as Scythians) were evolved from a proto-Eastern Iranic BMAC. And ancient BMAC (Aryan Iran_ChL) had direct ties with Kurdistan.
So, that means that Iranic people are not only linguistically linked, but also culturally and genetically linked to each other.
People of India and Pakistan are a different story. They are not Iranic, but mostly Indic/HINDU. They are just a mixture of people like Aryan Ezdi Kurds and Dravidians. But they are mostly Dravidian nowadays, though.
They don't speak a Western Iranic language. They speak a Hindu/Indic language that is closely related to Dravidian.
Kurds are Western Irani
Indians are Indic/HINDU, not even (Eastern) Iranic
So, very different from Kurds in the first place.
