What I know comes from decades with Emergency services. I also don’t eat sushi. I personally know people attacked by pits. I’d like to see the morons who own them jailed when their monsters hurt people. They are pathetically stupid dogs who are bred to turn fighting-vicious at the least trigger, like a silly young woman who leaned down to pet the 2-yr-old “rescue” and got her face chewed off. Mutilated for life. I hate these dogs, and I’m coming to hate the fools and “tough guys” who own them.
You have a lot of hate in you about this issue. I don’t think it’s possible to have an intelligent, let alone civil, conversation with you about Pit’s. You’re not only vested in your hate and dug in; you’ve demonstrated there’s nothing that could possibly convince you there are plenty of Pit’s who aren’t what you think they all are.
I’ll leave you with this one thought though. All dogs can hurt people; even those little yappy dogs I don’t care for. Medium to large dogs can break bones with their bite but they normally don’t; at least not without a good reason like they are protecting their human’s. There’s a mutual trust between dogs and people. When that trust is broken and the dogs are mistreated; we should not be surprised when they stop being “good dogs”.
