I studied the Pit Bull and found that it is not only how they are raised but, also their genetic lineage. Certain people in the not so past, inter-breed them for the aggression that they wanted for fighting. These dogs found their way into the population of dogs sold for pets. They have a genetic code of aggression that sooner or later finds it’s way to the surface.
Never ever trust a Pit. Even if you are a great owner,trainer.
Of course you are onto it. You see if, if Lefto-Science agrees with your conclusion, which of course they have in every other field, they might have to admit that there are ...gasp... like these "bad" people/dogs out there. Not only that, some human groups/dog breeds may even ....gasp ....have more "bad" people/dogs than others.
We simply can't have that
