“As they selected for performance, breeders could not know exactly which physical changes they were selecting for. But research now shows that selection for aggressive performance includes consistently selecting for very specific abnormalities in the brain. These abnormalities appear in many breeds of dog as an accident or anomaly, which breeders then attempt to breed out of the dogs. In the case of the aggressive breeds, the opposite occurred. Rather than excluding abnormally aggressive dogs from their breeding stock, breeders focused on creating lineages in which all the dogs would carry the genes causing them to reliably exhibit the desired impulsive aggressive behavior.”

Unfortunately, as the problem (gameness, or deadly impulsive aggressive behavior) has been bred into the PBT dog deliberately - along with strength and size and jaws and very hard head - I do not believe that it can be “trained” out.
To a hammer the entire world looks like a nail.
Stop being a hammer; try being the nail.
Put another way; if you are only going to look for the worst in someone - that’s all you will ever see.
It’s obvious your obsession is so ingrained and couple with your phobia about dogs that you won’t ever be cured of your mental illness. You simply won’t even acknowledge you have a serious mental health issue. Until you do you are destined to live this life of hate and fear. I wouldn’t want to be in your shoes for all the dog treats in Walmart.
