Why peshmerga did not want to protect Kurdish yarsani family? Because those Kurdish yarsani were not Muslims?

We condemn terror attack against yarsani family as the whole family was killed by the terrorists. Islamic Mohammad Rasul Allah's soldiers killed the all Kurdish Yarsani family members in a town near Kerkuk. Because we urge the international to protect the Yarsan people in northern Iraq.
Here on this video, Rudaw TV reveals the yarsani family's place and what weapons they had so isis knew they are not so many and attacked the Kurdish Yarsani family and killed all family members.
Some day ago some of Islamic Islamic brutal terrorist groups spoke Kurdish and had peshmerga clothes.
So those Islamists attacked yarsani family and killed the whole family near Kerkuk the Kurdish important city.
But a few days before the Islamic brutal terrorists were attacking yarsani family rudaw tv had interviewed the family and revealed how they yarsani defend themselves against Islamic brutal terrorists.
Right now we consider Rudaw TV as a participant against the Yarsani family.
At the same time we condemn peshmerga as a customer and did not want to defend the yarsani family despite them yarsani family has announced peshmerga and wanted help but peshmerga did not want to help the yarsani family.
Why peshmerga did not want to protect Kurdish yarsani family? Because those Kurdish yarsani were not Muslims?
