Insh Co. know you have him on your property?

We aint talking kids here. Thats the problem, Americans anthropomorphize their pets.
It's a ANIMAL ,with CENTURIES of selective breeding specifically for fighting in it.
Game ones are present day end line example of the best Dog Fighting K9 there is.
If you started all over breeding for a fighting dog - you'd end up with a pitt.
Make sure those animals cant get out if you know whats good for you.
Ok, you know, in a weird way, I have to agree with much of what you say---because its basically responsible pet ownership: don't let your pets run free, train them, have adequate fencing around your yard and so on.
I do not agree with your idea of pits having some unnaturally strong biting ability compared to other large dog breeds. They are a large powerful dog. No one is denying this. The thing is they will bite like a large powerful dog---one that is without a doubt capable fo hurting a human being, but not in some supernatural way. I've tried to present this from different angles to get you to understand they do not have any scientifically proven unique ability to bite harder than any other large breed of dog---from the standpoint of the one study done on pits biting (which I'll freely admit I think is flawed, but its the only study) to the standpoint of physiology/anatomy of their teeth as the limiting factor in a bite, to general attitude of a well socialized and trained dog. You still are holding onto the idea that they have some unnaturally strong biting ability. I'm not sure why, but I'm going to say it again, with the scientific evidence available, they don't when compared to other large breed dogs.
You also mention years of breeding as a justification for your thoughts on their supermouths. The thing is you really, really need to get away from the pitfighting part of that breeds history---which I'll agree with you is a very important part of creating the dogs we know today, but is not the only point--to fully understand the breed. Pit fighting was not the only activity these dogs were used for---they were used as a working, hunting, guardian breed and have been since the devlopment of the breed. On the frontier, pit bulls were an "all-purpose" dog. They herded cattle and sheep. They served as faithful family guardians, protecting families and livestock from the ever-present threat of thieves and wild animals. They served as companions. You absolutely have to aknowledge this if you are going to discuss the history of the breed.
You also mention the unwillingness to quit---I don't know if you have thought about it, but that is a trait of all hunting terriers, be it an APBT or an Airedale (a breed which was used by the German army to deliver messages in WWI because it would continue to attempt to deliver the message even after having limbs blown off by mortar rounds) or a rat terrier. When my parents bred black and tans and redbones for raccoon hunting, our pack leader was an Airedale for almost 11 years---because he wouldn't quit the hunt and he'd keep the pack going after the hounds were on the verge of giving up. Tenaciousness is a terrier trait, its not something specific to pitbulls, but is something shared by all terriers.
Finally the thing you need to consider is that pitbulls were not the only dog breed fought---what about Boston Terriers, "Wolf dogs" (including German Shepards and Malamutes), black and tan and blood hounds, and all of the others? Are they as bad of a "loaded gun"?
The bottom line is APBT's are large, powerful dogs. They are capable of damaging bites, just like any other large powerful dog breed. They should be owned by responsible pet owners, which includes people who take the time to train the dog for basic commands, leash walking, monitor the location of the dog--be it inside or outside--and above all don't allow their large dog to get into a situation where negative things could happen.
