Why people think so highly of them selfs? Mastiff Vs Human NO COMPETION!!??

my question is why do people think so highly of them selfs? English mastiffs, bullmastiffs, rottweilers, neos, french mastiffs, american bulldogs, and plenty other breeds can and WILL over power and out power a human no competion nomatter how heavy strong good of a fighter they are. They were bred to do that they must be good or they wouldnt be here. Also i have all of those dogs and more. Someone broke into my backdoor and had a pipe in there hands, they got pinned down by my bullmastiff. And english mastiffs and all the other dogs i mentioned could out power a human no competion. all breeds of Mastiffs were bred to guard or fight human. Also they were bred to OUT POWER AND OVER POWER A HUMAN NOMATTER WHAT. They were bred to pin them to the ground and Hold them there without them getting up. People think WAY WAY to highly of themselfs, Seriously. German shepherd do it all the time in police wotk, so do the others i mentioned. these dogs make shepherds look TINY.
