Maybe the time you spent chastising the breed after your failed attempt to socialize with it should have been more productively spent on self-introspection and 'reading' your own instincts with dogs. Failing to do so is only a disservice to yourself. A Thanks for taking time to express your views about life, dogs, and the Kuvasz. Most people won't spend as much time researching a dog as you did before you got your Kuvasz. Our goal is to help those people who will not research the breeds as thoroughly as you did.
Many people buy dogs on impulse or because of false claims about a dog's behavior.
I have seen many of these problem dogs and my understanding of the Kuvasz comes from training quite a few of them that in potential could have been good family dogs if they were owned by a person like you. I see firsthand the misfortune of improper socialization and misunderstanding of the breed character and protective behavior. I specialize in behavior modification, particularly aggressive behavior. Many dogs that come to me for training or evaluation have already bitten someone or exhibited other unacceptably aggressive behavior. Again, I would like to stress that in many cases, when I see a mature, aggressive Kuvasz it is due to the ignorance and incompetence of the owner.
