I can't say I will ever want a dog like that and I'm a pretty dang responsible dog owner..
I don't want that. I want as little possibility of dog aggression that I can find. I don't like it, I don't want to deal with it and it's not ideal for me, my life or the rest of my dogs. But, that doesn't matter.
Like has already been said, it's not bred for. It's a by product of breeding for the other traits that make them what they are. Are some dogs that have all those traits stone cold? Yes. Are most of them? Not at all. And to try and eradicate it from the breed would mean eliminating so many dogs that are exemplary examples of the breed just because if given a chance they would like another dog in their face. One of the biggest issues in so many dog breeds today is a small gene pool and you're asking that this breed have that done to them on an extreme scale.
Dog aggression is a reality of the breed and one that the majority of their owners understand, respect and expect from them so I guess I don't understand why if they are all happy with how their dogs are they should have to change it to fit your ideals
