That is untrue. Pit bulls were bred to fight, and even then, owners found it necessary to "toughen" them and make them mean to ensure that they would fight. Back when dogfighting was legal, dogs that showed aggression towards humans were culled. This is because three people were in the fighting ring with the dogs at all times. These people were the owners or handlers of the opposing dogs and a judge. Pit bulls were actually bred to not show aggression towards humans.
Please read the history of the dog type. Facts are readily available.
You will never find that I said the breed should be banned because I haven’t said that. I do think the tolerance of aggressive dogs should be zero.
