Most of what you've said here is downright drivel based in debunked hypothesis on dog behaviour.

They were never bred to be aggressive towards humans, and only a few lines were bred for blood sport. It's like trying to relate the hunting behaviour of a Finnish Spitz to a risk that it could also turn and kill humans.
Ah yes, because everyone knows that dog ownership is about physically dominating your dog, based on that oh-so-thorough and accurate study of captive wolves by 1 man.
Do you think the people training bears for movies, do so by physical domination?
People shouldn't own dogs PERIOD if they can't muster the ability to train them properly. Physically "dominating" (terrorizing) your dog doesn't do jack squat for its social behaviour and obedience, other than teaching it that it's always at risk of being physically manhandled, and scared dogs are dangerous.
Plenty of Pomeranians have zero training, since people just get them and let them develop into whatever cuz "so tiny it doesn't bother anyone"... Obviously, the neighbours would disagree after listening to a yapping dog for 8 hours every day.
