I agree with you. The controversy about their makeup and origin does not take away from their effectiveness as guardians.  It is my understanding that until recently it was very difficult to get a "real" Kangal dog from Turkey so westerners were sold the common working dog from "Anatolia" which we have come to know at the Anatolian Shepherd Dog. They have proven very effective as guardians and is now officially recognized in the American Kennel Club (AKC).
