They were not known for human aggression at all?
What are you smoking?
Based on pretty much any history of Pit Bulls that I’ve read, to believe what you just claimed, I’d have to believe that Pit Bulls were incredibly violent and aggressive toward people for much of their history, then during “the turn of the century” period you refer to, they weren’t known for being aggressive toward people, then later in the century began killing people at a rate several times higher than the rate of any other dog breed. And mauling people at a far higher rate than that.
And then I’d have to believe that just cracking down on dog fighters would solve the problem.
Logic isn’t your strong suit, mom.
The dog was used, historically, in BULL fighting - hence it’s name. It is not a dog with built in human aggression, however. Research is your friend.
Oh you know what - just keep drinking the koolaid the MSM serves up - just because you can see thru the Obama haze doesn’t mean you can see clearly on other things.
My dog breed today....your dog breed tomorrow....for whatever reason is convenient.
These are good animals being destroyed by bad...and stupid.. people.
