>>>The vast majority owned by responsible owners are gentle, loving dogs<<<
I STRONGLY disagree with this statement. A very large percentage are owned by irresponsible low-lifes or out and out thugs. These types are drawn to the breed because of its power or because it is a thug status symbol.
Another large percentage are owned by decent folks, who would do fine with a Beagle or Golder Retriever, but are by no means assertive enough, responsible enough, and experienced enough to handle an animal, which despite its many great qualities, is potentially, extremely dangerous.
I have little doubt you are a responsible owner who can handle your dog(s). But, that would put you in the minority of Pitbull owners, not the majority.
Perhaps. Pit bulls are generally not the dog of choice among families.
